What Is My Size at Glamourous?

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

Glamourous runs true to standard UK sizing as a general rule, so your usual size is a solid starting point — but there are a few important fit nuances worth knowing before you click 'add to bag', especially if you're shopping their bodycon dresses or structured occasion pieces.

I'll be honest — I came to Glamourous the way most people do: completely last-minute, hunting for something head-turning for a birthday night out with about three days to go. I'd seen their pieces all over Instagram, that brand signature of bold prints, curve-skimming silhouettes and a definite 'you will be noticed' energy. What I wasn't sure about was the sizing. Would the bodycon stretch enough? Would the drape work for my shape? Reader, it did. But I learnt a few things along the way that I genuinely wish someone had told me first — so here they are.

Who Is Glamourous?

If you haven't come across them yet, Glamourous is a UK-based fashion brand built almost entirely around occasion dressing. Think going-out looks, event outfits, holiday glamour — bold, beautiful, unapologetically dressy pieces across a wide size range, typically UK 6 through to 22 or 24 depending on the style. They're stocked widely via ASOS as well as their own site, which makes returns straightforward and sizing swaps far less stressful.

How Does Glamourous Sizing Run?

The short answer: broadly true to UK sizing — but as always, the details matter.

Dresses and tops — Generally true to size. If you're between sizes, most customers report that sizing up gives a more comfortable and flattering result, particularly in the bust and hip area.
Bodycon styles — These are designed to stretch and hug, so true to size or even a size down works if you prefer a tighter look. The fabric has excellent give, which is genuinely reassuring when you're unsure.
Structured and tailored pieces — Stick to your true size here, but do check the product description for any 'fitted' or 'relaxed' notes as these vary considerably by cut.
Petite and Curve range — Glamourous does a solid Petite and Curve range. The Curve pieces are cut specifically for fuller figures rather than just being a scaled-up standard, which makes a real difference to how garments actually sit on your body.
Footwear — Their shoes run standard UK sizing with no significant deviation reported by most wearers — no need to go up or down.

The Fabric and Fit Reality

One thing I genuinely appreciate about Glamourous is that their fabrics are chosen with stretch and drape firmly in mind — you're not fighting the garment, which makes sizing far less stressful than with a rigid, structured brand. Their signature slinky fabrics and velvet pieces in particular have real forgiveness in them.

That said, if you carry more of your weight on your hips or have a curvier silhouette, I'd always recommend measuring your hips before ordering a bodycon style and cross-referencing with their size guide. I once ordered a midi wrap dress in my standard 12 and the hip area was genuinely snug — not unwearable, but I'd have been significantly more comfortable in a 14. It taught me that wrap and ruched styles in particular can be unforgiving if you're hip-heavy. Lesson learnt the hard way, so you don't have to.

Styling Glamourous — and Where Else to Shop

Glamourous is firmly in the occasion-wear space, so if you're building a going-out wardrobe or need something event-worthy, they're a brilliant starting point. They work best when paired with complementary pieces from brands that understand the same occasion-dressing brief. Here's where I'd look:

High Street Picks

River Island — A natural companion to the Glamourous aesthetic. Their heeled sandals, occasion bags and going-out separates are well-priced and size up nicely alongside Glamourous dresses. Sizing runs true to UK standard.
Coast — A brilliant step up if you want something a little more refined. Their occasion dresses are cut for real bodies and their sizing is consistent and generous through the hip — a brand that rarely disappoints.
Phase Eight — Grown-up occasion dressing at its best. If Glamourous is the party, Phase Eight is the wedding. Sizing tends to be slightly generous, so consider sizing down if you're between sizes.
Warehouse — Genuinely underrated for going-out pieces. Their satin and ruched styles sit in a similar aesthetic to Glamourous but at very accessible price points. Sizing is standard UK and very consistent.
Ted Baker — Worth checking for occasion footwear and clutch bags to finish a Glamourous look. Their sizing runs slightly small, so go up half a size on shoes.
Monsoon — Great for more modest occasion styles or anything with a holiday or bohemian feel. Sizing is true to standard UK with a slightly relaxed fit through the body.
Reiss — When you want the same occasion energy but with a more polished, minimal edge. Worth knowing that Reiss sizes small, so I'd always recommend sizing up one here.

Premium Picks

Self-Portrait — Beautiful structured occasion dresses with serious cut quality. Sizes tend to run small, so go one size up from your usual. Worth every single penny for a special occasion — the quality is genuinely exceptional.
Nadine Merabi — One of my favourite occasion-wear labels right now. Crystal-embellished jumpsuits and gowns that are genuinely showstopping. Sizing is true to UK but with a fitted cut, so measure carefully before ordering.

Luxury / Designer

Roland Mouret — If Glamourous captures the spirit of being dressed up, Roland Mouret captures the architecture of it. Their bodycon cuts are iconic but sizes run small — most wearers go up one full size, so factor that in.

Independent Brands Worth Knowing

Rat & Boa — A cult independent label beloved by stylists for their slinky, luxurious occasion pieces. Gorgeous fabrics, true-to-size fit and a slightly more editorial feel than Glamourous if you want to stand out from the crowd.
Never Fully Dressed — A proper gem for occasion dressing and one I return to constantly. Their prints are bold, their cuts flatter curves beautifully, and sizing is true to UK across the range. An absolute must-explore if Glamourous is your vibe.

My Final Sizing Verdict on Glamourous

Order your standard UK size as a starting point — that really is the simplest and most reliable advice. If you're between sizes or curvier through the hips, size up for comfort, particularly in bodycon and midi styles. Their Curve range is a genuine standout if you're a UK 18–24, designed properly for fuller figures rather than simply scaled up from a smaller cut.

The brand's use of stretch-friendly fabrics makes it more forgiving than many occasion-wear labels, so don't overthink it — but do check the individual product's fabric content and cut description before ordering anything for a special occasion, especially if returns timings are tight. And if you're ever in doubt about your exact size? That's exactly what Tellar is for.
