What Is Sizing Like at Urban Threads?

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

Urban Threads runs broadly true to the standard ASOS own-brand size chart (UK 4–18, with Tall, Petite and Curve variants), but the catch is that fit varies wildly by style — slim-fit bodycons run snug, oversized shirts and t-shirts run genuinely oversized, and the satin and plisse trousers come up long. If you're shopping Urban Threads, the smartest move you can make is to read the product page tag — "slim fit", "oversized fit" or "regular fit" — before you click buy, because it tells you almost everything you need to know.

I've styled enough Urban Threads pieces over the years to have strong opinions, so let me walk you through what to expect, where it trips people up, and which brands you might want to compare against before committing.

A Quick Word on What Urban Threads Actually Is

Urban Threads is an ASOS own-brand label that sits firmly in the trend-led, going-out, sub-£40 territory. Think satin slip dresses, plisse trousers, ditsy floral mini dresses, oversized shirt dresses, skiwear in winter, and a frankly enormous swim and beachwear edit come summer. The brand pitches itself as confidence-inspiring outfits you'll reach for again and again — translation: party clothes and holiday wardrobe staples, with the occasional surprise like fleeces and ski jackets thrown in.

Because it's an ASOS in-house line, it follows the ASOS size chart and inherits all the same little quirks I've seen on its sister brands.

The Honest Sizing Verdict, Garment by Garment

Dresses

Bodycon and slim-fit dresses: Run true to size but unforgiving. If you're between sizes or carry your weight on hips and thighs, size up — these are designed to skim, not squeeze.
Oversized t-shirt and shirt dresses: Take your normal size. Resist the urge to size down "to make it less baggy" — the silhouette is the whole point and a smaller size kills the drape.
Floral mini and slip dresses: Slightly snug across the bust if you're a C cup or above. I'd nudge up one size if your boobs are doing more work than your waist.

Trousers

Wide leg and flared styles: Run true to size in the waist but long — the standard cut suits 5'7" and above. Anyone shorter should head straight to the Petite range.
Satin and plisse trousers: Often have an elasticated waist, so they're forgiving — but the rise is on the lower side, worth bearing in mind if you prefer a high waist.
Cargo and utility styles: Cut roomier through the thigh than your standard tailored trouser. Take your usual size; don't size down.

Tops, Co-ords and Knitwear

Crop tops and bralettes: Run small. I'd always go up a size if you're between two.
Oversized shirts and blouses: Genuinely oversized — there's no need to size up "for the look".
Lightweight knits: True to size but thin. They're not winter-warm, more layering-piece territory.

Swim and Beachwear

Bikini tops run small in the cup, generous in the band — fairly standard for high street swim.
Bottoms cut high on the hip, which is flattering but not for everyone — if you prefer a fuller coverage, size up.
One-pieces are body length dependent; if you're tall (5'8"+), the Tall edit is worth a look so you don't end up with a wedgie before you've reached the sun lounger.

A quick anecdote: I once styled a client for her hen weekend in a gorgeous Urban Threads satin slip dress, ordered in her usual UK 10. The dress arrived, the bust fit beautifully, but the slim cut clung to her tummy in a way she absolutely wasn't comfortable with. We swapped to a 12, and suddenly the same dress hung like a dream — flattering, languid, expensive-looking. Lesson learnt: with Urban Threads' slimmer-cut dresses, sizing up is almost always more flattering than sizing to fit your bust. Skim, don't squeeze.

Practical Tips Before You Buy

Always check the fit label on the product page — slim, regular or oversized changes everything.
Use the Tall and Petite editions if you're under 5'4" or over 5'8" — the standard cut is drafted for 5'5"–5'7".
Read the model height notes (usually under "Size & Fit") to gauge length on you.
Order two sizes if you're between — ASOS returns are still straightforward and it saves the heartbreak of "almost but not quite".
Bodycon and slip styles: if in doubt, size up. Always.

Brands to Shop Instead (Or Alongside)

Urban Threads is a great-value option, but it's far from your only one. If you're shopping a similar party-trend-holiday vibe, here are the brands I'd send a client to next.

High Street Picks

Bershka — Trend-led, sub-£40, and brilliant for going-out tops and party trousers. Sizing runs small, so size up one.
Stradivarius — A Spanish high street favourite for satin slips, plisse skirts and beach-ready linen. Sizing is true but cut for a slim Mediterranean fit.
Pretty Little Thing — The most obvious peer for occasion and going-out dresses. Watch for fit inconsistencies between styles.
New Look — Slightly more grown-up but a strong shout for satin slip dresses, floral minis and basics. Generally true to size.
River Island — Trend-led and a step up in quality from PLT. Their occasion dresses and tailoring are worth the slightly higher price.
Bershka Tall and Mango — Mango is the elevated everyday pick: cleaner lines, better fabrics, similar trend cues. Cut runs slim through the hip.
Monki — Edgier, more Scandi-cool than Urban Threads, but a great shout for printed dresses, satin separates and the kind of statement trousers that feel more premium than they cost.

Independent Picks (My Two Fresh Recommendations)

Damson Madder — A London-based indie doing trend-led pieces with a sustainability backbone. Their puff-sleeve dresses, satin skirts and printed sets are the natural step-up from Urban Threads if you want the same energy but in better fabric.
Never Fully Dressed — Bold prints, strong silhouettes, made in genuinely small batches. If you want a dress that won't show up on three other people at the wedding, this is the brand.

Premium

Whistles — For when you want the same satin slip or floral midi energy but in a fabric that'll survive more than a season.
AllSaints — Edgier, leather-leaning, party-perfect. Their slip dresses and tailored trousers punch well above the price tag.

Luxury

Self-Portrait — The forever-favourite for occasion dressing. If you've ever lusted after that lace mini at a wedding, this is the source.
Rotate Birger Christensen — Copenhagen cool meets party glamour. Sequins, satin, and silhouettes that read seriously expensive.

Final Thought from Me

Urban Threads is a brilliant entry-level option for trend pieces you don't want to break the bank on — the kind of dress you'll wear three times this summer and pass on next year. But its sizing tells a different story depending on whether you're buying an oversized shirt or a bodycon mini, and that's where most of the returns happen. Read the fit tag, check the model height, and if you're between sizes on anything fitted, size up. Your future self will thank you.
