Online Clothing Store: The Honest Guide (Sizing, Returns and Photos)
Fashion is the hardest ecommerce there is: the customer can't try anything on and returns 20% to 40% of orders. Everything else in the store revolves around that one problem.

Clothing is the best-selling category online and also the hardest to sell well. There's exactly one reason, and it has no technical fix: the customer can't try anything on. Everything you do in your store — the photos, the size chart, the copy, the exchange policy — exists to compensate for that gap.
Ignore it and you end up with a beautiful store, a 35% return rate and a margin that disappears into return shipping. This guide is about what genuinely moves the needle in fashion, not about setting up a generic store — that's covered in the complete online store guide.
The real problem: sizing
In fashion, 20% to 40% of orders come back, and the dominant reason isn't "I didn't like it" — it's "it didn't fit". Every return costs you outbound shipping, return shipping, inspecting the garment and putting it back into stock. Cutting five points off that rate is worth more than adding five points of traffic.
- Publish real measurements in centimetres, not just S/M/L. Chest, waist, hips, length — and which specific garment they were taken from.
- Say how it runs, in one honest sentence: "runs small, size up if you're between sizes". This saves more returns than any chart.
- State the model's size and height. It's the detail people look for most and almost nobody publishes.
- Describe the fabric and its stretch. Rigid cotton and cotton with elastane are bought very differently.
- Show the garment on more than one body if you can. It cuts returns and widens your audience.
Photography: the only substitute for a fitting room
In fashion the photo doesn't accompany the product — the photo is the product. Nobody buys a garment they can't see properly, and the visual standard you're measured against isn't the shop down the street, it's the big brands that same customer scrolls past every day.
- At least four shots per garment: front, back, fabric detail, and one in context.
- A consistent background across the whole catalogue. Visual coherence signals seriousness before any copy does.
- Faithful colour. A blue that turns out to be a different blue guarantees a return and a bad review.
- Real zoom that lets people see the stitching and the texture of the fabric.
- A shot of the composition label. It sounds unglamorous; it answers a lot of purchase doubts.
The technical setup — lighting, background, file size, how many photos before the store slows down — is in product photography for online stores. For clothing, add one rule: be true to the colour before you're beautiful.
Product pages that answer the real questions
A clothing page that only says "Long-sleeve blouse — $29" leaves the customer with six unanswered questions, and every unanswered question is an exit. These are the fields people genuinely read, in order of importance.
| Field | What it must say | What it prevents |
|---|---|---|
| Measurements per size | Real centimetres for every size stocked | The wrong-size return |
| Composition | Fabric percentages | Surprise at the texture, and allergies |
| Care | Washing, ironing, tumble dryer | Complaints about damaged garments |
| How it runs | Small, true to size or large | The doubt that stalls the purchase |
| Model reference | Height and size worn | The customer's mental calculation |
| Stock per size | What's left and what isn't | The frustration of reaching checkout and failing |
| Delivery time | Real days to their city | The "when will it arrive?" messages |
| Exchanges | Window and who pays shipping | The abandonment that comes from distrust |
Returns and exchanges: the cost nobody calculates
This is the most important economic decision in a clothing store, and it deserves to be made with numbers in hand before you publish the policy. Free exchanges sell more, but only if your margin can carry them.
| Policy | Effect on sales | Effect on margin |
|---|---|---|
| No exchanges | Noticeably lowers conversion | Protects margin and destroys repeat purchase |
| Free size exchange, once | Clearly lifts conversion | Bearable when margin is above 50% |
| Full return with refund | Converts best of all | Only viable with high margin and your own catalogue |
| Exchange in a physical shop | Builds trust with no shipping cost | The best balance if you have a storefront |
Stock by size and colour: the operational pain
A clothing store doesn't manage 40 products: it manages 40 products × 5 sizes × 3 colours = 600 combinations. That's why fashion stores break operationally long before stores in other categories do.
- Every size-colour combination is its own stock unit, with its own code. Don't improvise this later.
- Show sold-out sizes, don't hide them. A struck-through M informs; a missing M confuses.
- Sync with the shop floor if you also sell physically. Selling online something just sold in-store is the worst service failure there is.
- Photograph by colour, not by style. A customer who wants the green one needs to see the green one, not imagine it.
- Check stock before every campaign. Advertising what you don't have burns budget and reputation at once.
On shipping — rates, real timelines, what to promise — the regional reference is ecommerce logistics and shipping in LATAM. In fashion the timeline matters especially: clothes are bought with an occasion in mind, and arriving late is the same as not arriving.
What it costs to launch and where to start
Building a clothing store isn't more expensive than any other store; the content is what's expensive. Photographing 40 products across several colours is the big line in the budget, and it's also the one you shouldn't cut.
- Start with 20-30 well-photographed items, not 200 badly resolved ones.
- Invest in the photo shoot before you invest in advanced features.
- Leave the full catalogue for phase two, once you know what actually sells.
- Test on WhatsApp or Instagram first if you haven't validated demand yet — how to do that properly is in selling on WhatsApp.
Frequently asked questions
What's a normal return rate for clothing?
Between 20% and 40% depending on the category: basics come back less, fitted garments and footwear considerably more. If you're above 40%, the problem is almost always sizing or photo colour, not the product. Start by reviewing those two things before changing anything else.
Do I need a model, or is the garment on white enough?
A white background is useful for detail, but the garment worn sells far more because it answers how it drapes and how it fits. Ideally you have both. If a tight budget forces a choice, choose the garment worn — and always state the height and size of the person wearing it.
Should I sell on a marketplace or on my own store?
It isn't either/or, and in fashion the combination usually works: the marketplace brings volume and discovery, your own store brings margin and a customer relationship. The full comparison, with the costs of each, is in marketplace or your own store.
How many products do I need to launch?
Twenty well-executed items are enough, and better than a hundred half-done. A small catalogue with excellent photos, real measurements and reliable stock converts better than a large one with incomplete pages. It also lets you learn what sells before committing inventory.
