Buying designer clothes online used to feel like a gamble. You either paid full price at a department store, or you took your chances on a marketplace and hoped the parcel that arrived resembled the photographs. That has changed — but not evenly. The five retailers below all sell genuine designer clothing, and they are not remotely interchangeable. One is the best place in the world to find a discontinued Bottega bag; another will get a new-season Lemaire coat to your door in two days; a third will undercut everyone on price and ask you to accept a longer wait and a thinner safety net.

We have shopped with all five over the past two years, and this is our honest read on who each one is actually for — including where they let you down.

The quick comparison

Swipe the table sideways to see every column on a phone.

1. The RealReal — for the pieces nobody makes any more

The RealReal's real advantage is not price — it is inventory that does not exist anywhere else. If you want a discontinued Céline trapeze from the Phoebe Philo years, a Margiela piece from a collection that ran once, or a coat in a colourway the brand made for a single season, this is where you look. Everything is authenticated in-house by trained specialists rather than by an algorithm, which is why it remains the platform most people trust for four-figure handbags.

The condition grading is the part we have come to rely on. Items are described in genuine detail — corner wear, interior marks, whether the hardware has been polished — with photographs of the flaws rather than only the flattering angles. In two years of buying we have had one item arrive worse than described, and it was refunded without argument.

The caveats are real. Prices on desirable pieces are set by what the market will bear, so a popular bag can cost more here than a rival platform. Return windows are short and some pieces are final sale. And if you are shopping from outside the United States, the shipping and duty picture gets complicated quickly.

2. SSENSE — for contemporary labels, done properly

SSENSE occupies a specific and valuable position: it carries the designers that sit between the big houses and the truly obscure. Lemaire, Our Legacy, The Row, Rick Owens, Jil Sander, Dries Van Noten, alongside a deep bench of labels most department stores will not touch. If your taste runs to good cutting rather than obvious logos, this is the most reliably interesting edit online.

Two things make it worth paying full price. The first is the photography and the product copy — measurements are given properly, colours are accurate, and the flat shots tell you what a garment actually looks like rather than how it drapes on one model. The second is that the operation simply works. Orders arrive quickly, packed well, and the returns process is genuinely painless.

It is not cheap outside the sale periods, and the sale is where SSENSE becomes remarkable — reductions run deep, twice a year, across labels that rarely discount elsewhere. Set an alert for your sizes and be ready to move, because the good pieces go in hours.

"I stopped buying designer clothing at full price the day I learned to shop three sites at once. The same jacket can vary by four hundred pounds depending on which boutique happens to be holding it."

3. Cettire — the cheapest prices, and the trade-off that comes with them

Cettire is the one that makes people suspicious, and the suspicion is worth addressing directly. It routinely undercuts everyone else on new-season designer pieces — not by five per cent but sometimes by thirty — and it does this because it operates as a marketplace, sourcing from a wide network of boutiques and wholesalers rather than holding stock itself.

That model is legitimate, and in our experience the goods have been genuine. What it also means is that you are further from the item than you think. Delivery takes longer because the parcel often ships from a third party. Stock occasionally turns out not to be there after you have paid. And the returns policy is the weakest of the five here — narrower windows, return shipping at your expense, and a customer-service experience that has drawn consistent criticism online.

Our advice is to use Cettire for what it is genuinely good at: a known quantity in a size you are certain of, where the saving is large enough to justify the friction. It is not the place to gamble on a fit you are unsure about.

4. Mytheresa — when you want it handled

Mytheresa is the opposite proposition to Cettire. You will rarely find a bargain, and you will almost never have a problem. It is a genuine luxury retailer with buyers who edit hard, which means the selection is narrower than a marketplace and considerably more considered — the three coats they carry from a house are usually the three worth owning.

What you pay for is the service layer. Next-day delivery in most major markets, immaculate packaging, free returns that are collected from your door, and a customer-service team that resolves things in one email. For a first significant designer purchase — the kind where you want to be able to send it back without a fight if the shoulders are wrong — that is worth real money.

The sale is also better than its reputation suggests, particularly on the more directional labels that do not sell through at full price. And their size guidance is unusually accurate, which matters enormously when a single garment costs more than a month of rent.

5. FARFETCH — for finding your size when nobody else has it

FARFETCH works differently again: it connects you to hundreds of independent boutiques and brand partners around the world, and shows you their stock in one place. The practical consequence is coverage. When a piece has sold out everywhere in a UK 10, there is a decent chance a boutique in Milan or Seoul still has one, and FARFETCH is how you find it.

That breadth is also the thing to understand before you order. Because the seller is an individual boutique rather than FARFETCH itself, the experience varies — delivery times, packaging quality and the returns process all depend on who is actually shipping to you. Check the seller and the stated dispatch time on the product page before committing, particularly on anything time-sensitive.

Used deliberately, it is the most powerful search tool in online luxury. Used carelessly, it is the one most likely to produce a parcel that takes two weeks and arrives in a plain box.

How to actually choose between them

The mistake most people make is picking a favourite retailer and shopping there by habit. The five above are good at genuinely different things, and the money is saved by matching the purchase to the platform.

If the piece is current season and you know your size, check Cettire first and FARFETCH second — that is where the price spread lives. If you want it quickly, or it is expensive enough that you want a proper safety net, buy from Mytheresa or SSENSE and treat the extra cost as insurance. If the piece is discontinued, archival, or simply better than anything currently in production, The RealReal is usually the only realistic option.

Two habits are worth building regardless of where you shop. Learn your measurements — actual centimetres for shoulder, chest and sleeve — rather than relying on a size label, because sizing varies more between designers than between retailers. And before any significant purchase, spend three minutes checking the same item across two of these sites. In our experience that single habit saves more money than any sale alert, any discount code, and any loyalty scheme yet invented.

None of these retailers is the best one. The best one is whichever matches the specific thing you are trying to buy — and knowing the difference is what turns online designer shopping from a gamble into something closer to a skill.
