Does Quiz Run Small? Should I Size Up? Your Complete Sizing Guide

Yes, Quiz generally runs small across most categories—particularly dresses, bodycon styles, and anything with minimal stretch—so sizing up is usually recommended, especially if you're between sizes or prefer a more comfortable fit. I learned this spectacularly at a friend's wedding when I ordered my "usual size" in a Quiz dress online, only to discover I literally couldn't zip it past my ribs. The emergency trip to Debenhams for a replacement dress (RIP Debenhams) whilst my makeup artist waited is not a memory I cherish. Quiz makes gorgeous, affordable party wear, but their sizing requires strategic navigation.

Understanding Quiz's Sizing Reality

Quiz is a British high street brand specializing in occasionwear, party dresses, and going-out pieces at accessible prices. Their aesthetic is glamorous, trend-focused, and unapologetically feminine. However—and this is crucial—their sizing skews small, particularly compared to mainstream high street brands.

I'm a fairly consistent size 12 across most UK retailers. In Quiz? I'm reliably a 14, sometimes a 16 in bodycon styles. It's not a reflection on your body—it's genuinely how they size their garments. Understanding this upfront saves disappointment, emergency shopping trips, and that horrible feeling of "have I gained weight?" (you haven't—the sizing is just tight).

How Quiz Sizing Compares Across Categories

Dresses (The Main Event)

Quiz dresses are their hero product, and unfortunately, they're also where the sizing runs most consistently small. Bodycon styles, sequined numbers, and fitted midi dresses all run at least one size small—sometimes two sizes for anyone busty or curvy.

Lipsy, Quiz's main competitor in the affordable party dress market, runs similarly small. Both brands cater to a going-out aesthetic, and both seem to size for a very specific body type. Boohoo, the fast fashion giant, actually runs slightly more generously than Quiz—I can usually wear my regular size in Boohoo dresses, which says a lot about how tight Quiz runs.

Dorothy Perkins, the classic British high street brand, runs substantially more generously than Quiz. A size 12 in Dorothy Perkins will fit completely differently to a Quiz size 12—expect to size up at least once, possibly twice. New Look (mentioned in a previous post but relevant here) sits somewhere in between—more generous than Quiz but less forgiving than Dorothy Perkins.

Bodycon and Fitted Styles

This is where Quiz gets really unforgiving. Their bodycon dresses, bandage styles, and anything described as "figure-hugging" run extremely small. If the fabric has zero stretch (some Quiz pieces use relatively rigid materials despite being fitted), size up two sizes without hesitation.

Missguided, another fast fashion brand targeting the same market, creates bodycon styles that are fractionally more forgiving than Quiz. Pretty Little Thing runs similarly tight to Quiz—both brands seem to assume their customers want clothing that's essentially painted on.

Tops and Blouses

Quiz tops and blouses run small, particularly through the bust and shoulders. Anything fitted or tailored will need sizing up. Looser, floaty styles are slightly more forgiving but still run smaller than typical high street sizing.

Kew, a lovely British brand with feminine, vintage-inspired pieces, runs more true to size than Quiz. Their tops and blouses are cut with more generous proportions. Hollister, despite being aimed at a younger market, actually has more consistent sizing than Quiz—their relaxed styles run fairly standard UK sizing.

Trousers and Skirts

Quiz trousers and skirts run small, particularly in the waist. Their high-waisted styles can be especially unforgiving if you've got any tummy at all (spoiler: we all do). Waistbands tend to have minimal stretch, which compounds the sizing issue.

Lands End, the American heritage brand known for quality basics, runs substantially more generously than Quiz. Their sizing is designed for comfort and wearability; Quiz sizing is designed for... well, I'm not entirely sure what. River Island (mentioned before but important comparison) runs more true to size than Quiz—you can usually stick with your regular size there.

Outerwear and Jackets

Quiz coats and jackets also run small, particularly tailored styles. If you plan to layer knitwear or shirts underneath (which, in the UK, you absolutely will), size up at least once.

Timberland, known for outdoor wear, creates outerwear with proper room for layering. Their sizing philosophy is completely opposite to Quiz's skin-tight approach. Superdry (mentioned earlier but relevant) runs more generously in outerwear than Quiz, with actual room for movement.

When to Definitely Size Up

• You're between sizes: Always go with the larger size in Quiz

• The item is bodycon or fitted: Size up at least once, possibly twice

• You're busty: Quiz doesn't cut generously through the bust—size up

• The fabric has no stretch: Rigid fabrics in tight cuts are a disaster waiting to happen

• It's for an important event: Don't risk it—size up for peace of mind

• Reviews mention sizing: If multiple people say "runs small," believe them

The Rare Times You Might Stay True to Size

• Oversized or relaxed styles: Quiz's intentionally loose pieces can accommodate your usual size

• Stretchy jersey or elastane-heavy fabrics: The stretch provides some forgiveness

• You prefer very fitted clothes: If skin-tight is your aesthetic, your usual size might work

How Quiz Compares to Similar Brands

ASOS (mentioned before but worth repeating) stocks Quiz alongside their own label, and the sizing difference is stark. ASOS Design runs more true to size with better consistency. If you're shopping both brands, expect to be at least one size larger in Quiz.

H&M (also mentioned previously) runs substantially more generously than Quiz. Their sizing is more aligned with European standards and tends to be forgiving. Quiz is the opposite—unforgiving and tight.

Zara, another European brand, has inconsistent sizing but is generally more generous than Quiz. Even Zara's fitted pieces have more ease than comparable Quiz items.

Real Talk: The Quiz Shopping Strategy

Here's my honest approach to buying Quiz after years of trial and error:

• Automatically size up once: This is my baseline for any Quiz purchase

• Read every review: Customer feedback about sizing is invaluable

• Check the fabric composition: Less than 5% elastane? Size up twice

• Order two sizes if possible: Quiz offers free returns—use this to your advantage

• Allow time for returns: Don't leave it until the day before an event

• Try in-store if you can: Seeing how different sizes fit is enlightening

How Tellar Eliminates Quiz Sizing Stress

Right, here's why Quiz's sizing drives me to distraction: their pieces are genuinely lovely. At £30-£60 for a party dress, they're accessible. The styles are on-trend, the embellishments are gorgeous, and they photograph beautifully. But the sizing anxiety is real, particularly for special occasions where you can't risk a wardrobe malfunction.

The Bottom Line

Does Quiz run small? Absolutely yes. Should you size up? In 95% of cases, definitely. How much should you size up? At least once, possibly twice for bodycon styles or if you're busty.

Quiz makes beautiful, affordable occasionwear, but their sizing is genuinely challenging. Don't let it put you off—just factor it into your shopping strategy. Use Tellar to get accurate sizing recommendations, read customer reviews obsessively, and when in doubt, size up.

Your future self, standing in front of the mirror in a Quiz dress that actually zips up comfortably, will thank you. Trust me—I've got the emergency Debenhams receipts to prove why this matters.
