Buy a swimsuit online – 5 things to check

When you buy a swimsuit online, five things determine whether the purchase is a success: size guide and fit, return policy, material description, customer reviews, and delivery time. Check all five points before you order – that way you avoid mistakes and get the swimsuit you actually want.

Why is it harder to buy a swimsuit online than in a store?

A swimsuit fits close to the body, and fit is everything. In a physical store you can try things on in a minute – online you depend on the information the webshop provides. Some shops give you everything you need; others leave you in the dark with vague size descriptions and a return fee that makes it expensive to change your mind.

That doesn't mean buying online is risky – quite the opposite. Once you know what to look for, it's actually easy to find the perfect swimsuit from home. You save time, you can compare styles at your own pace, and you order straight to your door. It's about choosing the right webshop and asking the right questions before you click "buy now".

Below you'll find the five most important checkpoints – and a concrete overview of what MAYAS does to make your online purchase as safe as possible.

The 5 things to check when buying a swimsuit online

1. Size guide and fit – find your exact size

The single most important checkpoint. A swimsuit that's one size too large provides neither support nor a flattering look. One size too small is uncomfortable and impossible to wear for long. A good webshop provides a detailed size guide with measurements in centimeters – not just S/M/L.

Grab a measuring tape and measure your bust, waist, and hips. Then compare with the webshop's size chart. If the webshop doesn't offer that information, that's a red flag.

At MAYAS you can use the Fit Finder guide to find the style and size that suits your body type. It takes into account your measurements, your body shape, and the type of swimsuit you're looking for.

2. Return policy – what happens if it doesn't fit?

No return policy or a short return window is a deal-breaker when buying clothing online. For swimsuits this goes double, because fit is so crucial. Always check: How many days do you have to return? Is return shipping free or paid? Do you get your money back or only a gift card?

MAYAS offers a 30-day return policy. That gives you plenty of time to try the swimsuit on, see how it looks in natural daylight, and decide whether it's right for you – without any time pressure.

3. Material description – what is the swimsuit made of?

The material determines whether a swimsuit holds its shape, holds its color, and feels comfortable against your skin – even after many swims. Good signs are that the material is specified (not just "polyester"), that it is OEKO-TEX 100 certified, and that the manufacturer is named.

Avoid swimsuits where the product description is vague or where there is no information about the material's origin at all. Cheap materials wrinkle, lose elasticity, and can in the worst case irritate your skin.

MAYAS swimsuits are made from Italian materials and are OEKO-TEX 100 certified, meaning the fabric has been tested for harmful substances and is safe against the skin.

4. Customer reviews – what do other buyers say?

Product photos are styled and edited. Customer reviews are reality. Check whether the webshop has a trusted review system, and read what people say about fit, quality, and customer service. One negative pattern that recurs across many reviews is a signal you shouldn't ignore.

Look especially for comments about: Does the sizing run true? Does the material hold up after washing? Is customer service easy to reach? What do people say about the return process?

MAYAS has an average customer rating of 4.8 stars and has passed +10,000 swimsuits sold. Both figures say something about a product that lives up to its promises.

5. Delivery – when will you receive your swimsuit?

If you're ordering a swimsuit for a holiday starting in two weeks, delivery time is critical. Check whether the webshop clearly states when you can expect delivery – and whether there is tracking information so you can follow your parcel.

MAYAS delivers to Denmark within 1–2 business days of ordering, and all orders over 500 DKK ship for free. Order on a Monday morning and you'll typically have your swimsuit by Wednesday.

The checklist in brief: size guide with centimeter measurements ✓, minimum 30-day return policy ✓, named and certified material ✓, verified customer reviews ✓, clear delivery time ✓. Webshops that meet all five are the ones you can shop with confidence.

What are the most common purchasing mistakes, and how do you avoid them?

Most swimsuit purchasing mistakes online aren't about bad taste – they're about missing information at the time of purchase. Here are the three most common scenarios and how to avoid them.

Wrong size

The classic mistake. You order your usual size, but the manufacturer measures differently from what you're used to. The solution is simple: measure yourself in centimeters and compare with the webshop's size chart – and use the Fit Finder if it's available. Never order based on S/M/L alone.

The material disappoints in real life

A product that looks great in photos can feel cheap in your hands. Certifications like OEKO-TEX 100 and information about the material's origin give you a real indication of quality. If material information isn't available, the risk is high.

You change your mind – but the return window has closed

Short return periods (7–14 days) don't give you enough time to try the swimsuit properly – for example in daylight, with the right underwear underneath, or on a day when you have time to really assess it. A 30-day return policy is the minimum if you want to shop with peace of mind.

Overview of MAYAS styles – which one is right for you?

How MAYAS makes buying online safe

Many women are hesitant to buy a swimsuit online – because they've experienced opening a parcel that didn't live up to expectations and paying a return fee that cost almost as much as the product itself. MAYAS is built on a different premise: that you should be able to shop with complete confidence from home.

30-day return policy, no questions asked

You have a full month to make up your mind. Try the swimsuit on, feel the material, test the fit. If you're not satisfied, you return it. No lengthy explanations required.

Free shipping over 500 DKK

Orders over 500 DKK are delivered free to your door. It makes perfect sense to order two styles at once and return the one you don't want to keep – shipping costs are zero, and you have both options on hand when you make your decision.

1–2 day delivery in Denmark

You won't wait a week for your order. MAYAS delivers to Denmark within 1–2 business days, and you receive tracking information so you can follow your parcel the whole way.

At MAYAS you can buy a swimsuit online with complete peace of mind: 30-day return policy, free shipping over 500 DKK, 1–2 day delivery, and a Fit Finder to help you with sizing. +10,000 swimsuits sold and an average customer rating of 4.8 stars confirm that the concept works.
