Be You Size Guide: What Size Am I in Be You? UK Fit Advice & Personalised Sizing Help

e You

is a modern fashion brand designed to empower every woman to feel confident in her shape—whether through curve-hugging dresses, everyday basics, or loungewear that fits as well as it flatters. But with such a wide size range, frequent stock drops, and varied product types, figuring out what size you actually need in Be You can be challenging.

This guide breaks down how Be You sizing works, what to expect from fit and structure, and how Tellar.co.uk—the UK’s leading free sizing tool—can give you a personalised size recommendation in seconds.

Is Be You True to Size?

Yes, Be You is generally true to UK sizing—but with fit variation depending on fabric type and silhouette.

Here’s what to keep in mind:

Bodycon and fitted styles: Cut close to the body, especially around the waist and hips. Some shoppers find these run slightly snug—especially if unlined or made from thick jersey or ribbed fabric.
Stretch basics: Flexible and forgiving. Stay true to size unless you’re between sizes, in which case you can size down.
Loungewear and co-ords: Looser cuts and elasticated waists usually offer a relaxed fit.
Trousers and cargos: Often structured at the waist and hips—if you're curvier through the hip or thigh, you may need to size up for comfort.

With Tellar.co.uk, you don’t need to second-guess. Our system compares your bust, waist and hip measurements against Be You’s actual product data—so you always get the right size, based on your body.

Be You Size Conversion Chart

Be You Size	UK Size	Bust (cm)	Waist (cm)	Hips (cm)
XS	UK 6	80–84	63–66	86–90
S	UK 8	85–88	67–70	91–94
M	UK 10	89–92	71–74	95–98
L	UK 12	93–96	75–79	99–103
XL	UK 14	97–102	80–85	104–109
XXL	UK 16–18	103–109	86–93	110–116

This chart is a helpful reference—but sizing is rarely one-size-fits-all. If your hips are a size 14 and your waist is a size 10, which do you go with? That’s exactly the kind of problem Tellar.co.uk solves.

Sizing by Category: What to Expect from Be You

1. Dresses & Jumpsuits

Be You’s signature category. Think ribbed midis, fitted minis, and curve-accentuating jersey styles. Expect:

Close fit through bust, waist and hip
Mid-stretch fabrics, often unlined
Sizing consistency across styles

Stick to your usual size unless you want a more relaxed drape—then consider sizing up. If your hips are fuller in proportion to your bust/waist, you might need to size up for comfort.

2. Loungewear & Co-ords

Joggers, cropped tees, oversized sweatshirts. These are typically true to size or relaxed:

Waistbands tend to be elasticated
Tops are cut boxy or cropped
Soft stretch materials

Size down for a more sculpted look or up for comfort. Tellar.co.uk will show you your best match based on your hip-to-waist ratio—which matters more than you think in loungewear fit.

3. Tops & Bodysuits

These pieces vary by fabric:

Ribbed or fitted jersey tops: Slightly snug. Stretchy but clingy—size up if in doubt.
Oversized t-shirts: Generally generous in fit—some users prefer to size down.
Bodysuits: Pay attention to torso length as well as bust/waist. If you’re long in the body, sizing up can help avoid pulling or gaping.

4. Trousers, Joggers & Bottoms

This category includes wide-leg trousers, joggers, cargos and figure-hugging flares. Fit tips:

Waists run true to size, but hip and thigh proportions vary by style
Cargos may feel tight across the seat—especially in rigid fabrics
Stretch bottoms offer more leeway, but check inseam and rise

If your lower body is proportionally fuller than your waist, Tellar.co.uk will guide you to the size that balances both.

Why Be You Sizing Can Feel Inconsistent

It’s not just you—many women report that their size changes across different Be You products. That’s not a quality issue—it’s a category and fabric issue.

For example:

A size Medium in a cotton jogger may feel very different from a Medium in a stretch midi dress
Cropped tees have more give than bodysuits
Lounge sets vary depending on whether they’re jersey, ribbed, or fleece-backed

Rather than guessing, let Tellar.co.uk do the work. We compare each product’s fit behaviour to your actual body measurements and provide a real-time size match.
