What’s My Clothes Size at Boohoo? Does Boohoo Run Big or Small?
Does Boohoo Run Big or Small?
Boohoo generally runs small, especially in:
Bodycon and occasion dresses
Corset and structured tops
Fitted trousers and jumpsuits
However:
Joggers, hoodies and oversized shirts often run true to size or generously
Stretch jersey and co-ords are forgiving and can run large
Outerwear varies—some puffers are roomy, others snug, depending on cut
If you're between sizes, curvy, or fuller-busted, it's common to:
Size up in non-stretch and structured garments
Size down in oversized or stretchy styles
Boohoo is one of the UK’s biggest fast-fashion retailers, known for trend-led clothing at ultra-affordable prices. From bodycon dresses and two-piece co-ords to oversized hoodies, tailored jumpsuits and curve-accentuating denim, Boohoo offers fashion-forward pieces that change with the season—and sometimes with the week.
OTHER GREAT BRANDS TO TRY:
The Couture Club - If you're after that streetwear-meets-glam vibe, this is your brand. Their matching co-ord sets and velour tracksuits have serious cult status on the club scene, sitting right alongside Gym King and SikSilk.
Never Fully Dressed - The go-to for bold prints and party glamour, especially their bestselling wrap dresses that have a proper following. The versatile wrap styles are everywhere on nights out – think Pretty Little Thing but with more personality.
Little Mistress - Sequins, embellishments, and bardot necklines galore. Their embellished maxi dresses punch well above their price point - brilliant for weddings and big nights without the Lipsy or Club L price tag.
dv8 fashion - Brilliant for festival season and last-minute bodycon dresses when you need something now that won't break the bank, in the same bracket as Boohoo and Missguided.
Juicy Couture - The Y2K comeback is real, and Juicy's iconic velour tracksuits are back with a vengeance. Those diamanté hoodies are having a moment – it's giving Fila and Ellesse but make it 2003.Why Boohoo Sizing Feels Inconsistent
1. Ultra-Trend-Driven Fit
Boohoo’s fashion DNA is rooted in:
Snatched waists
Thigh-slit dresses
Cut-outs, ruching, corsetryAll of which mean fit is intentionally tight and figure-hugging—especially at the bust, waist and hips.
2. Fast Production Model
New styles are dropped daily. But that means garments:
May follow different fit blocks depending on the supplier
Might vary slightly in measurements across seemingly similar products
3. Limited Product Notes
Most product pages don’t explain whether something runs small or large—so guessing becomes inevitable unless you use a tool like Tellar.co.uk.
Boohoo also offers Petite, Plus and Tall ranges—but the base fit across most core products still assumes:
Narrow shoulders
Standard torso length
True-to-label sizing only if you fall within their average proportions
That’s why Tellar.co.uk is the easiest way to shop accurately.
