Fashion and beauty webshop UX: what makes people buy

We're Design by Karina, a strategy-first boutique Shopify agency in Rotterdam for premium fashion and beauty brands. We design and build Shopify stores for brands across the Netherlands and Belgium, and we turn what makes your brand different into a reason to choose you. If you came here looking for a UX designer for your fashion or beauty webshop, this is how we think about it. Below is the checklist we use, page by page, with examples from stores we designed and built, so you can use it on your own store whoever you work with.

What makes people buy from a fashion webshop?

Someone buying fashion online can't try the piece on, so your store has to do that job for them. This is what fashion ecommerce UX comes down to.

• A size chart next to the size selector. In centimeters, and not hidden in the footer, because the size selector is where people start to wonder. More in Size charts that reduce returns.

• Fit notes in plain words. Something like "fits tight, take one size up" or "the model is 1.75 m and wears an S", so people can compare it with their own body.

• Stock per size, so nobody picks a size and then finds out it's sold out.

• Filters by size, color and fit on every collection, so people only see what they can buy.

• Returns in one line under the button. How long, how it works and who pays, because that's the safety net that makes ordering feel okay.

• Photos on a body, from the front, the side and the back, plus one close-up of the fabric, so people can see how it falls and what it's made of.

Take VYOLA, a Belgian atelier that makes body jewelry by hand and to measure. Online, the big question was trust: how do you order something made for your body when you can't try it on first? So right by "add to cart", the product page has a size chart in centimeters, a field for your own measurements and a fit guarantee with free adjustments. And someone buying a gift who doesn't know the size gets an easy way out, the gift card. A fashion buyer has the same question, even with a much simpler product.

What makes people buy from a beauty webshop?

A beauty buyer wants to know it will work for them, and that it's safe on their skin.

• Advice by skin type or concern, so people find their product and not every product you sell.

• Ingredients and how to use it, easy to find and not in a wall of text.

• Reviews with skin type or age, so people see someone like them.

• A routine or bundle that shows what goes with what, so nobody has to work that out alone.

• Honest comparisons with the alternatives people are already looking at.

• Trust signals near the button: delivery, returns and safety information. I go deeper into this in Building trust in your webshop.

On Zourani, an LED face mask store we designed and built, that meant a selector by skin concern on the homepage, a comparison table on the product page and a step-by-step ritual. For the full layout, read Beauty product pages: ingredients, routines, reviews and bundles.

Which pages matter most, and what goes on each?

Every page has one question to answer, and it helps to look at your store that way. For the product page on its own, read What makes a product page that sells?.

Why is mobile first for fashion and beauty?

Fashion and beauty are often browsed on a phone, in between other things. So we design every page for a thumb first: the size or skin answer early on the page, the button within reach, photos you can swipe and a checkout you can finish with iDEAL in a few taps. If a page only works on a desktop, you lose people right at the moment they're interested. More in Mobile first: your webshop on the phone.

How do you keep a store premium and still selling?

Premium and conversion aren't opposites. A premium store sells by being clear rather than loud, with fewer words that mean more, calm space, real photos and one action per section.

What breaks the feeling are the tricks, like fake countdowns, pop-ups the moment someone arrives or "only 2 left" when it isn't true. They might win you one order, but people remember how a store made them feel, and that's hard to win back. Every store we design starts with the same questions: who is buying, what do they need to know, and what helps them choose your brand? So each choice on the page has a reason, not just a look.

Good to know in the Netherlands

Those tricks aren't only a brand problem here. The ACM says what you tell people about availability or popularity has to be reliable, so "only 2 left" has to be true, and a countdown timer can only run if the offer ends when it says it does. A discount has to be calculated from your lowest price of the 30 days before it. Options shouldn't be ticked in advance unless that's the best choice for the customer, and the order button has to make clear that clicking means paying, because the word "Order" alone isn't enough. Since June 2026, webshops selling to consumers also need a clear button or link to undo a purchase online. And for Dutch buyers, the checkout should show iDEAL, now seen as iDEAL | Wero. More in Shopify, iDEAL and Wero.

How do you organize a catalog so people find things?

Think about how your customer searches, not how your warehouse is organized. Thereza Pedrosa Gallery shows contemporary art jewelry, and collectors follow the artist first and the piece second. So we organized the store around the artists, with a page per maker, and kept product types as a second way to browse for people shopping for a gift. In fashion that might be by occasion or fit, and in beauty by skin concern or routine step. What matters is that the store is sorted the way your customer already thinks.

What happens after launch?

Your store is never really finished. People use it in ways you didn't plan, and the most useful information about a store only arrives once real customers start using it. That's what our Growth Plan is for. We review available data, identify friction in the customer journey and make prioritized improvements over time, one thing each month, and you get a report of what changed. Depending on the plan, that includes A/B testing.

The Growth Plan is also open to stores we didn't build. We start with a Store Audit, where we go through your Shopify store the way your customers do, and from there we know what to work on first.
