What Is Sizing Like at Quiz?

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

Quiz clothing runs generally true to size, with a tendency to come up small in fitted and bodycon styles — so if you're planning to wear anything figure-hugging to a wedding, a night out or a work Christmas party, it's worth sizing up one as a precaution. The brand is one of the UK's go-to destinations for affordable occasion wear and going-out looks, and the sizing is mostly reliable once you understand where the quirks are.

I've had quite a few clients ask me about Quiz over the years — usually in a mild panic the week before an event, having ordered their usual size and found it too snug. It's a brand that does glamour brilliantly at a genuinely accessible price point, but the cut is deliberately form-fitting across most of its range, and that means the sizing leaves less room for error than something like a floaty midi from a high-street staple. Go in informed and you'll do well.

Quiz Size Conversion Guide

Quiz uses standard UK sizing, which makes conversions reasonably straightforward. The brand runs from a UK 6 up to a UK 28 across much of its range, which is genuinely commendable for an occasion-wear brand at this price point.

💡 Ella's tip: If you're between sizes at Quiz, always go up — especially in anything with a structured bodice, a fitted waist, or any kind of boning. These styles have zero extra room built in, and squeezing into a smaller size will show. Trust me: I've seen it, and it's never worth it when the size up would have looked genuinely great.

Sizing by Category — The Real Picture

Quiz's range is heavily occasion-focused — think sequin midi dresses, lace going-out tops, tailored jumpsuits and bodycon everything. Here's how the sizing actually plays out across the key categories:

Bodycon & Fitted Dresses: This is Quiz's bread and butter, and where sizing is most critical. These styles run small — sometimes by a full size — because the stretch fabric is cut to sit flush against the body. If you're fuller through the hips or bust, size up without hesitation. The dresses are designed to show your shape, not squeeze it.
Midi & Maxi Dresses: More forgiving than the bodycon styles, and generally true to size. Floatier fabrics and less body-skimming cuts mean you're less likely to need to adjust. That said, if a midi has a fitted bodice combined with a full skirt, size to your bust and let the skirt take care of itself.
Occasion Jumpsuits: These are notoriously tricky across every brand, and Quiz is no exception. Size to your widest measurement — usually hips — and have the waist taken in if needed. The leg length runs on the longer side, which is helpful if you're tall, less so if you're petite.
Going-Out Tops & Blouses: True to size in most styles. If a top has a structured or boned bodice, apply the same rule as the dresses and size up one.
Tailored Trousers & Skirts: Generally true to size with a mid-rise cut that works for most body shapes. Wide-leg styles are the most forgiving; cigarette and straight-leg cuts are trimmer through the thigh.
Coats & Outerwear: True to size or slightly generous — Quiz outerwear is cut with enough room to layer underneath, which is sensible. If you want a very fitted look, go down one; otherwise your usual size is fine.
Curve Range (UK 16–28): Quiz's curve range is one of its genuine strengths — the styles are not watered-down versions of the main range, which is something that can't be said for all brands at this price point. Sizing within the curve range follows the same logic: true to size in looser styles, size up in anything fitted.

✨ Styling note: Quiz does occasion glamour best when you lean into it fully. If you're wearing a sequin Quiz dress to a wedding or black-tie event, keep everything else simple — minimal jewellery, one pair of heels, a neat clutch. The dress is meant to do the work. Over-accessorising a heavily embellished Quiz piece is the one styling mistake I'd steer you away from every time.

My Honest Stylist Take on Quiz

Here's the thing about Quiz — it gets a bit of a snobbish reception in some fashion circles, and I think that's genuinely unfair. For affordable occasion wear that actually delivers on the glamour front, it's hard to fault. The sequin dresses, the lace midi styles, the ruched bodycon numbers — they photograph well, they hold up for a night out, and the price point means you can wear something once and not feel guilty about it.

Where I'd temper expectations: the everyday basics and workwear pieces aren't as strong as the occasion range, and the fabric quality reflects the price — you're not buying longevity here. But for a birthday dinner, a hen do, a wedding guest outfit on a strict budget, or a festive party look, Quiz absolutely earns its place. The key is buying the right size and styling it with confidence.

One thing I genuinely rate: their commitment to an inclusive size range. Running up to a UK 28 across a meaningful selection of styles is something a lot of more expensive brands still don't manage, and that matters.

The Best Alternatives to Quiz — At Every Budget

Whether you're after something with a touch more fabric quality, a broader size range, or simply a different aesthetic for your occasion-wear needs, here are my picks:

High Street Alternatives

Phase Eight — The go-to for elevated occasion wear on the high street. Their dresses are beautifully cut, consistently well-reviewed in Vogue and Harper's Bazaar for wedding guest looks, and the sizing is reliable and honest throughout. A definite step up in fabric quality from Quiz.
Monsoon — Particularly strong for print-led midi dresses and occasion pieces with a more bohemian, feminine edge. The quality at this price point is impressive and they run a generous size range. Perfect if you want something a little less bodycon.
Coast — A brilliant option for more formal occasion wear — think black-tie, weddings and smart events. Their structured dresses and jumpsuits are among the best on the high street for fit and finish.
Warehouse — Trend-led and affordable, with a strong going-out and occasion range. A very close aesthetic neighbour to Quiz, but with slightly better fabric quality and a more consistent fit across sizes.
River Island — Great for going-out looks and occasion dressing with a fashion-forward edge. Their sequin and embellished styles are popular for a reason — well-made at the price, and sizing tends to be reliable.
Oasis — Now online via Next, Oasis still delivers beautifully on occasion dresses and event-ready separates. Their midi lengths and wrap styles are especially flattering and size consistently true.
New Look — Brilliant for affordable occasion wear in a wide size range, up to a UK 24 in most styles. Their sequin and occasion pieces regularly feature in best-buy roundups for exactly this market.

Premium Alternatives

Reiss — A significant step up in construction and fabric. Reiss occasion wear — particularly their tailored jumpsuits and occasion dresses — is exceptionally well-reviewed and the fit is notably more precise than fast fashion brands. Worth the extra investment for a big event.
Ted Baker — Famous for its event-dressing credentials and consistently flattering cuts. Their occasion dresses are beautifully finished, the sizing is slightly generous which is welcome, and the brand has strong coverage in the occasion-wear press.
LK Bennett — The ultimate British destination for polished occasion wear. Worn on royal engagements, at Ascot, and at more weddings than I can count. Sizing runs true, construction is excellent, and the investment per wear is genuinely strong.

Independent & Left-Field Picks

Chi Chi London — An independent British occasion-wear brand that occupies almost exactly the same market as Quiz but with slightly more considered detailing and a genuinely impressive extended size range (up to a UK 26). Their lace midi dresses and embellished styles are regularly featured in occasion-wear edits by Grazia and OK! Magazine. Worth bookmarking if Quiz is your usual go-to.
Rixo — A step up in price but a major step up in quality and originality. Founded in London by two friends, Rixo makes stunning print-led occasion dresses that are a world away from the high-street formula. If you're dressing for a wedding, a garden party or any event where you want to be genuinely remembered, Rixo delivers every time. Sizes UK 6–18.
