What Is Sizing Like at Galvan?

Galvan runs small. Its eveningwear is cut slim and structured — especially through the bust, waist and across the hip on those gorgeous bias-cut gowns — so if you’re between sizes, or you carry a little more on top, my advice is to size up. The label is marked in UK sizes, but the actual fit leans distinctly European, which is precisely the sort of thing that trips people up when they order online.

I’ll be honest: I learned this the hard way. A few years ago I ordered a Galvan satin slip in my usual size for a friend’s black-tie wedding, felt smug that I’d sorted my outfit weeks early… then couldn’t do the thing up over my ribcage. One frantic exchange later (and one size up), it fitted like a dream and I’ve worn it to about six events since. Lesson learned, and now I pass it on.

Why Galvan Fits the Way It Does

Galvan London was founded in 2014 by four women who wanted modern, red-carpet-worthy eveningwear without the red-carpet price tag. The house is built on precision tailoring and fluid, sculptural lines — and that precision is exactly why fit matters so much here. These aren’t forgiving, billowy pieces; they’re designed to skim the body and hold a clean silhouette.

The cut is slim: bodices and waists are engineered close to the body, so there’s little ease to play with.
The bias is unforgiving and brilliant: bias-cut silk clings and moves, which is flattering but means any tightness shows.
The sizing leans European: a UK 12 here can feel closer to a snug 10 elsewhere.

How the Different Styles Fit

Galvan isn’t one fit across the board, so here’s how I’d approach the key pieces:

Slip dresses & satin gowns: true to size if you’re straight up and down, but size up if you’re between sizes or fuller-busted. The bias does the flattering; the room comes from going up, not down.
Tailored pieces & suiting: sharp and fitted through the waist. If you like a relaxed line or want to layer underneath, take the next size up.
Jumpsuits & halternecks: check the torso length, not just the dress size — these are cut long and lean.
Bridal & occasion gowns: order early and allow for a fitting. Never leave a Galvan gown to the last minute; the tailoring deserves a tweak.

My Styling Advice

The whole point of Galvan is quiet impact, so let the cut speak. I keep accessories minimal — a fine gold chain, a clean heel, hair off the face — and let that liquid silk do the work. For anyone nervous about a column silhouette, a bias slip is genuinely the most forgiving shape going: it glides past the middle rather than clinging to it. And if a gown feels a touch snug across the bust when it arrives, that’s your signal to exchange, not to “diet into it” the week before. Comfortable confidence always photographs better than a dress you can’t breathe in.

Where to Shop the Galvan Look

If you love the Galvan aesthetic — fluid slips, clean occasion tailoring, understated glamour — here’s where I’d shop across every budget.

High Street

Whistles — my first stop for minimal, modern slip dresses; the cuts feel genuinely directional rather than fussy.

Phase Eight — reliable for flattering occasion dresses that skim and elongate.
Hobbs — elegant, polished pieces with a grown-up sensibility that suits black-tie.
Massimo Dutti — unbeatable for that elevated, pared-back European feel on a high-street budget.

Premium

Reiss — sharp tailoring and sleek slip dresses; the most Galvan-adjacent of the lot for clean lines.
LK Bennett — refined occasion dressing with a real eye for elegant silhouettes and shoes to match.
Me&Em — clever, considered cuts designed to flatter; great for a relaxed-luxe column.
Mint Velvet — relaxed slip dresses and easy satin separates with that effortless, lived-in glamour.

Luxury & Designer

Totême — the queen of the understated, expensive-looking silhouette; pure quiet luxury.
Khaite — for sculptural, body-conscious eveningwear with serious presence.
Stella McCartney — fluid, modern occasion pieces with a conscience, in a similar mood to Galvan.
