How to Spot a Quality Bikini: Seams, Lining, Elastic and Fit
ยท 3 min read
At first glance, many bikinis can look alike. But the difference between one that lasts a season and one that stays with you for several summers is quality.
Knowing how to spot a quality bikini is key to making a good purchase. It's not just about design, but technical details that affect how it fits, how it behaves in the water and how long it stays in good condition.
In this guide we explain how to recognise a quality bikini by looking at the things that really matter.
1. The seams: the most telling detail
Seams are one of the first signs of quality.
On a well-made bikini:
the seams are straight and even
there are no loose threads
there's no visible pulling in the fabric
they're reinforced in key areas
Poor seams can cause a bikini to lose its shape or tear with wear.
2. The lining: key to comfort and durability
The inner lining is essential, although it often goes unnoticed.
A good bikini should have:
a lining that's soft to the touch
a double layer where needed
a good fit to the body
The lining prevents see-through moments, improves support and makes the bikini feel more comfortable.
3. The elastic: support without discomfort
The elastic is what keeps your bikini in place.
A quality bikini will have:
firm but flexible elastic
good recovery (it springs back into shape)
no feeling of constriction
If the elastic is too weak, the bikini will stretch out. If it's too strong, it'll dig in and feel uncomfortable.
4. The fit: the real test of quality
You can have good fabric and good design, but if the bikini doesn't fit well, it doesn't work.
A good fit means that:
the bikini adapts to your body
it doesn't shift when you walk or swim
it doesn't dig in or squeeze
it keeps its shape
5. The fabric: more important than it seems
The material has a direct effect on the bikini's quality.
Look for fabrics that are:
stretchy but strong
soft to the touch
good at recovering their shape
made for salt water and chlorine
A quality fabric keeps its shape and colour for longer.
6. How it reacts to water
You really notice a quality bikini when you wear it.
It should:
dry relatively quickly
not lose its shape when wet
keep its fit in the water
not go see-through
This is one of the key points that sets a good bikini apart from a basic one.
7. Details that make the difference
Small elements show whether you're looking at a quality bikini:
clean finishes
securely attached straps
sturdy fastenings
no visible defects
These details often go unnoticed, but they're decisive.
Quality bikini vs basic bikini
Basic bikini
simple seams
weaker fabrics
less durability
a poorer fit
Quality bikini
better construction
durable materials
a carefully developed fit
a longer life
How to know if it's worth investing
A quality bikini may cost more, but it also:
lasts longer
fits better
keeps its shape
gets worn more
Conclusion: you can see (and feel) quality
Recognising a quality bikini isn't complicated if you know what to look for: seams, lining, elastic, fabric and fit.
These are the elements that decide whether a bikini simply looks goodโฆ or really works.

Shall we play? ๐ Take my **quick test** and I'll tell you **your perfect bikini**: the one that best suits your skin, hair, figure and style.
I get it, choosing a size online is a bit scary! ๐ But it's easy: you pick the **top and bottom separately**, from XS to L. If you're between two, **go for the bigger one**. To get it right, take the **ยซWhat's my size?ยป** test: under a minute and **no measuring**.
Good question! We try to keep our sizes **like the big fashion brands**, so you'll usually wear **your usual size**. If you're between two, **go for the bigger one**.
Oh, I'm so sorry! ๐ For now our sizes go **from XS to L**: we don't have XXS or XL. If you're unsure of yours, take the test and I'll tell you **which fits you best**.
Let me tell you! Almost all our tops tie **at the neck and at the back**, so you adjust them to your body. Right now, the ones with **ties to adjust** are the **Revolve, Sheriff, Howdy and Wild West**; in other designs the bottom has an **adjuster** for a perfect fit. And all tops come with **cups (not padded)**, with an opening to remove them or add padding.
I totally get it, finding a bikini with good support is a real challenge! I'd go for the **sporty** or **triangle** tops, which **give great support**, and since almost all of them tie at the neck and back, you can make them **fit you perfectly**.
Don't worry! The **thong bottom isn't tiny**. And the **basic one is Brazilian style**: slightly cheeky but not too much, **just enough to flatter** ๐ If it's a tie-side, you can also adjust it at the sides.
I love that you asked! ๐ All our bikinis are **handmade**, most of them **in Portugal**. We source **the best fabrics in Europe**, mostly with **recycled fibres**, and every year we review our patterns **millimetre by millimetre**.
Not at all! ๐ **None of our bikinis are see-through**: they're all **lined** and come with **cups**, so nothing shows, not even wet or in light colours. If you don't like the cups you can remove them, and there's a pocket for padding.
Good question! It depends a lot on **how you care for it**. We use **the best fabrics in Europe** and test them for months, but it's normal for the metallic finish to lose some shine over the summers. To make it last: **hand wash it** (never in the machine), **don't dry it in the sun** or the dryer, and in winter store it **completely dry in its fabric bag**.
I love that you want to look after it! ๐ This way it'll last **many summers**:
๐ซงAlways hand wash it inside out, in cold water with a little soap only on stained areas. Never in the washing machine.
๐ซNo bleach, fabric softener or stain removers, and never in the dryer.
๐ค๏ธDry it inside out, in the shade and without pegs, with the elastics relaxed so they don't stretch.
๐In winter, store it completely dry in its fabric bag (included with every order).
Not at all! **They don't stretch out** ๐ Just dry them **without pegs** and with the elastics relaxed, and they'll last you **many summers**.
Yes! **All our bikinis are lined** ๐ค

We'll send a courier and **deduct the pickup from your refund**.

Yes! ๐ With the **Quelton gift card** you choose the amount and she chooses **the bikini of her dreams**. Perfect for birthdays, anniversaries, Secret Santa or a just-because gift.

Oh, what a shame! ๐ We usually **don't restock**: when a bikini sells out, **it's gone**. That's how we keep things **exclusive** and you **unique**. What I do recommend is joining the **waiting list**: if we ever restock, **you'll be the first** to know.
Right now **we don't make made-to-measure** or personalised bikinis. But since you **choose the top and bottom separately** and almost all **tie to adjust**, it'll fit **almost made-to-measure**! ๐
Can't wait for you to see them in person! ๐ We don't have our own shop, but you can find us at **several stockists** ๐๏ธ Which **city** would you like to see them in? Type it and I'll tell you the nearest ones.
Love that you want to be featured! ๐ธ To appear in **#IconicQueltons** or on our website, **tag us** in your photos, posts or stories: **every Friday** we share the photos of those who tag us on Instagram.
How exciting that you'd like to stock our brand! ๐ We carefully select **the very best stockists**. If you're a **multi-brand store**, our dedicated page has more information and you can **request a quote and purchase terms**.
I love that you asked! ๐ **Quelton** comes from our surname: we tried a thousand combinations until we found it, and the moment we read it, **we fell in love**.
We started in **2020** as a hobby, and in **2025** we left everything to follow our dream: making bikinis that fit well ๐ **Thanks to you** we're here today.
We call it **iconic**! ๐ It's the pattern we started with, which is why it's so special. We bring it back **every year** with new metallics, lurex and **prints we design ourselves from scratch**. Want to see all our iconic bikinis?
The **Bronze**! ๐ซ It's a chocolate shade that **goes with everything** and **never goes out of style**: a staple you should have in your wardrobe. Just know **it always sells out**โฆ
Yes! ๐คฉ Over the years we've worked with **Carlota Maraรฑรณn, Lola Lolita, Aitana Soriano and Elena Gortari**, and even the stylist of **Aitana, the singer**, got in touch to style our bikinis for her music videos and trips! It's all on our **Wall of Fame**, along with the press we've been featured in.
We make **around 100 units of each design**, and almost all **sell out at launch** ๐ฅ So if you fall for one, **don't leave it for tomorrow**.
With your order we give you a **premium fabric bag** ๐ to keep your bikinis in a drawer over winterโฆ or to carry your spare bikini or anything else to the beach.
Yes! **It dries super fast** โ๏ธ So you go from the water to your towel, and from your towel to the beach bar, without staying wet for hours.
It depends what you're after! ๐ If your **legs are on the shorter side** and you want them to **look longer**, go for the **thong bottom**: it really lengthens the leg. If you prefer a bit more coverage, the **basic** is **Brazilian style**: slightly cheeky, **just enough to flatter**.
Great idea, the tan matters too! โ๏ธ I'd go for a **triangle top** with a **thong bottom**: it leaves the **fewest tan lines** and a **gorgeous tan**.
Love that you're so active! ๐ For **padel, surfing or beach volleyball** I'd go for the **sporty**, for the **support of the top**. Any **iconic triangle** with its **tie-free** bottom also works great, it doesn't move at all.
Don't worry! **They all stay in place** ๐ You can dive in and jump the waves **without a care**.
What a plan! ๐ฅ **Any of them works**: the best part is **each of you wearing your own**, with your own colour and styleโฆ and all of you looking **iconic**! ๐
Yes! ๐ And since almost all **tie to adjust** and you **choose the top and bottom separately**, you can adapt them to your body at every stage.
Of course! You can **mix them however you like** ๐ That said, right now we don't have the same colour across different designs for a perfect match, so I'd recommend **buying the full set**: it's designed so **everything matches**.
That's exactly why we do it this way! ๐ You can choose **one size for the top and another for the bottom**, so it fits **your body perfectly**. If you're unsure, take the **ยซWhat's my size?ยป** test and I'll tell you both.
We generally **don't do reservations or pre-orders**, unless we launch a **special offer**. To be the first to hear about launches, join the **newsletter** or follow us on **Instagram and TikTok** ๐
Of course! ๐ You can order **two sizes**, try them on at home and **return the one that doesn't fit** (within **14 calendar days**, with the hygiene sticker intact).
We **don't offer gift wrapping or notes** right now, but if you need it, email me at pedidos@queltonshop.com and we'll see how we can help ๐
**You don't need an account** to buy ๐ But if you create one, you **keep all your orders** and it's **much easier to exchange or return**.
We **don't run giveaways** right now ๐ But if you join our **newsletter**, you get a **discount on your first order** ๐
We **don't have an ambassador, points or refer-a-friend programme** right now ๐ But if you wear Quelton, **tag us**: you could appear in **#IconicQueltons**!
Haha ๐ The best way to make your ex **regret it**: a Quelton, a sunset and some beach stories. Nothing else needs to be said ๐ฅ
**Ibiza and Formentera** are our favourite places in the world! ๐ด For those coves I'd go for a **metallic**: it shines beautifully in that sun, and in photosโฆ I won't even tell you โจ
**Beach club** plans! ๐ฅ Stylist's trick: a **metallic or lurex** bikini with a **skirt or shorts** on topโฆ and from the towel to the party **without going home** ๐
I **totally** get it ๐ My sister and I felt exactly the same: we couldn't find a bikini that fitted us wellโฆ **that's why we created Quelton**. Patterns fine-tuned **millimetre by millimetre**, top and bottom **in your size** and fabrics that **flatter your figure**. You'll feel **confident and stunning**, I promise.
Hi gorgeous! ๐ How can I help? Type anything or pick below ๐
Thank you! ๐ Anything else, I'm right here. **No basic. Stay Iconic. Be Quelton** ๐
If the **second** bikini doesn't work for you either or you want to return it, that shipment **is on you**: send it to our warehouse yourself.

Email us at pedidos@queltonshop.com with your **order number and address**: we'll arrange the pickup and **deduct that shipping from your refund**.
