What Is Sizing Like at Pretty Lavish?

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

Pretty Lavish runs true to size across most of its range and follows standard UK sizing from a 6 to a 22 — but their occasion and bodycon styles in particular can come up slightly snug through the bust and hips, so if you're between sizes, I'd always recommend sizing up for a comfortable, camera-ready fit. This is a brand built for big nights and special occasions, and you want to feel amazing in these dresses — not be tugging them all evening.

I've been recommending Pretty Lavish to clients for a few years now, particularly when they're hunting for wedding guest outfits or bridesmaid dresses that actually look expensive without the designer price tag. The brand has carved out a genuinely impressive niche in the UK occasion wear market — think beautifully draped midis, floaty maxi dresses, and structured corset styles that photograph brilliantly. But the one thing I always tell people before they order: know your measurements, not just your usual size label, because the fit can vary noticeably between styles.

Tip: Pretty Lavish includes model height and the size worn on most product pages — always check this before ordering. Their models are typically 5'8"–5'10", so if you're petite or on the shorter side, pay close attention to the dress length description too. A midi on the model might be a near-maxi on a 5'4" frame.

About Pretty Lavish

Pretty Lavish is a British occasion wear brand that launched in 2013 and has grown into one of the most recognisable names in the UK wedding guest and event dressing space. It's entirely online, which has allowed it to keep prices remarkably reasonable for the quality — most dresses sit in the £60–£130 bracket, which for the cut and fabrication on offer is genuinely good value.

The brand is particularly well known for its bridesmaid collections, its ruched satin styles, and its ability to produce trend-led occasion pieces that feel current without being try-hard. Over the last few years they've also expanded into knitwear, co-ords, and everyday occasionwear, broadening beyond just the going-out dress bracket. Their inclusive size range — up to a UK 22 — is also worth applauding. It's not a brand that treats sizing above a 16 as an afterthought.

How the Sizing Works — Garment by Garment

Occasion Dresses & Midis

This is Pretty Lavish's heartland and where you need to be most attentive with sizing. Their ruched and bodycon-adjacent styles — typically in satin or jersey — are cut to sit close to the body, which is the whole point aesthetically. But if you're fuller in the bust or hip, you may find your usual size is tighter than comfortable. I always tell clients: order your true size and one up, try both, and return the one that doesn't work. Their ruching is very forgiving to the eye even in a slightly larger size — that's actually the genius of the design.

Maxi Dresses

The floatier, more draped maxi styles — often in chiffon or crepe — are more forgiving in terms of fit and generally come up true to size. If you have a longer torso or are on the taller side, these tend to work beautifully. For petites, I'd check the length carefully; some styles do have adjustable straps which helps enormously.

Bridesmaid Dresses

Pretty Lavish's bridesmaid range is one of their strongest offerings, and they size well for group orders — the consistent sizing across the range means it's relatively straightforward to order different sizes for different bridesmaids without the fit looking inconsistent across the group. For bridesmaid orders specifically, I'd recommend everyone takes their measurements rather than going on dress size alone, since these are often purchased months in advance of the wedding when bodies may change slightly.

Tops, Knitwear & Co-ords

Their casual and everyday pieces tend to be more relaxed in cut and generally run true to size or even slightly generously. Their knit co-ords and wide-leg trouser sets have been a particular highlight recently — great quality for the price, and the sizing is consistent. If you prefer a looser, more relaxed fit in knitwear, you could size down; if you want the oversized look, go true to size.

Jumpsuits

Jumpsuits are always the trickiest category for fit because you need everything to align at once — shoulders, bust, waist, hip, and crotch length. Pretty Lavish's jumpsuits tend to run true to size but can be short in the body for taller women. If you're above 5'8", check the measurements carefully. If you carry your proportions in your hips, size up — the waist can always be belted in.

My Honest Verdict on Pretty Lavish Quality

For the price point, the quality is genuinely impressive — particularly the satin and crepe occasion pieces. The fabrication feels more expensive than it is, and the photography on the site does a good job of reflecting how the clothes actually look worn. I've seen clients in Pretty Lavish at weddings who've had guests asking where their dress is from and being genuinely surprised at the price. That's the best possible endorsement. They're not heirloom pieces, but for one or two big wears? Absolutely worth it.
