What Is My Size at Femme Luxe?

By Ella Blake — Fashion Stylist | Tellar Fashion Hub — Always honest, unbiased, & unsponsored post

Femme Luxe runs small — and I say that from personal experience. The first time I ordered from them I stuck with my usual size 10 and spent an awkward five minutes trying to zip myself into a bodycon midi that had absolutely no intention of budging past my hips. Since then? I always size up at least one. For most shoppers, going up one to two sizes from your usual UK size is the golden rule at Femme Luxe, and it genuinely makes the difference between a disaster return and a really great outfit.

Understanding Femme Luxe Sizing

Femme Luxe is a UK-based brand, so their labelling follows standard UK sizing — but the cut runs noticeably tighter than the high street average. Their core range runs from a size 6 through to a size 22 (or XS–3XL), which is a solid inclusive spread, but the fit philosophy is very bodycon and close-cut throughout. Even their more relaxed styles tend to have a snatched, fitted quality to them.

A few things I've noticed working with Femme Luxe pieces:

Dresses and co-ords — almost always come up small. If you're between sizes, go up.
Tops and bodysuits — can vary by fabric. Ribbed styles are stretchy and more forgiving; woven styles are not.
Knitted pieces — tend to have a bit more give, but the cut is still quite fitted through the torso.
Trousers and skirts — size up if you carry weight on your hips or thighs. The waistbands are often elasticated which helps, but the seat and thigh area can be restrictive.

How to Get Your Femme Luxe Size Right

The most reliable way to shop Femme Luxe is to use your measurements — bust, waist, and hips — and cross-check those against the Femme Luxe size guide on their product pages rather than going by your usual brand size. Every style's individual fit notes are worth reading too, as Femme Luxe do include guidance like "model wears a size 10" along with the model's measurements, which is actually really useful context.

If you're a true in-between, err on the side of larger. The fabric blends they use — lots of polyester, viscose, and stretch jersey — mean sizing up doesn't leave you swimming in fabric; the pieces still cling and drape as they're designed to.

Petite and Plus-Size Shoppers

Femme Luxe is genuinely one of the better affordable brands for plus-size and curvy shoppers — their size range goes up to a 22/3XL and the styles don't change dramatically at larger sizes, which is refreshing. That said, I'd still advise checking individual product reviews, as some cuts are more generous in the hips and bust than others. If you're petite (under 5'4"), their dresses do come up long — a midi on a model tends to hit full-length on shorter frames, so bear that in mind before ordering.

Brands With More Consistent Sizing — for Reference

One of the frustrations of online shopping is that sizing inconsistency isn't unique to Femme Luxe — it's almost universal across the high street. Here's how some of the brands I regularly recommend compare:

River Island — runs fairly true to size, with a slightly curvier cut through the hips. Brilliant for jeans and occasion dresses.
New Look — generally consistent and good for petite and plus ranges. Very comparable price point to Femme Luxe.
ASOS — sizing varies wildly by brand stocked, but their own-label ASOS Design pieces tend to be reliable and they have an exceptional returns policy if things don't work out.
Topshop (now online only) — runs slightly slim, good for straight and athletic frames.
Urban Outfitters — tends to run large, particularly in their basics. A size down is usually right here.
H&M — sizing has improved a lot in recent years. Their conscious and divided lines are worth checking for quality basics at a Femme Luxe-friendly price.
Mango — runs on the smaller side, similar to Femme Luxe in that respect. Gorgeous quality step up from the ultra-fast fashion price bracket.
Zara — famously unpredictable. Always check the specific garment. That said, their knit and jersey pieces are usually more generous.

A Step Up in Quality — Premium Picks

If you love the style of Femme Luxe but want something with a bit more longevity, these premium brands nail the same aesthetic with a better fabrication:

Reiss — exceptional for bodycon and tailored pieces that feel elevated. Sizing is true to UK standard and really consistent.
Whistles — beautifully cut dresses and co-ords with a more grown-up, understated edge. True to size and made to last.
Me&Em — arguably the best investment for versatile, smart-casual pieces. Sizing is generous and reliable.

My Two Independent Brand Picks

I always like to shout out a couple of brands that deserve more attention than they get:

Rebellious Fashion — a fantastic UK indie brand that occupies the same affordable, trend-led space as Femme Luxe but with slightly more generous cuts. Great for going-out pieces and co-ords, and their sizing tends to be a touch more reliable.
Club L London — if you love Femme Luxe's occasion-wear angle, Club L is the natural next step up. Still very accessible in price, but the fabric quality and fit finish are noticeably better. Sizing runs true to UK standard which is a relief.

Luxury Options for a Special Occasion

When the occasion calls for something truly special — and you want a piece that'll see you through more than one season — these are the names I turn to:

Self-Portrait — stunning occasion dresses with impeccable sizing and construction. True to UK size throughout their range.
Roland Mouret — the master of the bodycon silhouette done properly. Expensive, but the fit is extraordinary.
