Bonmarché is a trusted UK high-street name, catering specifically to women seeking stylish, flattering, and affordable clothing — particularly in sizes 12 to 24 and beyond. With a loyal customer base and a reputation for wardrobe staples, Bonmarché is popular with mature women looking for clothing that prioritises comfort and fit.
But even with inclusive sizing, shoppers often ask: does Bonmarché run big or small?
This guide offers a detailed breakdown of Bonmarché’s sizing across different product categories, real customer feedback, and how Tellar.co.uk helps you find your exact Bonmarché size — plus your size in over 1,500 other brands — using just your body measurements.
Who Shops at Bonmarché?
Bonmarché focuses on real women’s bodies, offering size ranges from UK 10 to 28, with select lines extending to size 32. Their clothing is particularly popular with:
-
Women aged 45+
-
Curvier and plus-size customers
-
Shoppers prioritising comfort, value, and flattering fits
Their in-house brands — including Julie Walters, Lorraine Loves, and Ann Harvey — provide cuts tailored to mature figures, often with longer lengths, softer fabrics, and practical stretch.

Tip: Bonmarché garments often have added stretch or elastic waistbands — making them more forgiving than traditional high-street tailoring.
Sizing by Fabric & Fit Type
-
Viscose blends & jersey: Add natural give — true to size or slightly generous
-
Denim & cotton twill: Size down if stretch is built in
-
Structured jackets: Less forgiving — size up if between sizes or fuller busted
-
Knitwear & loungewear: Cut for comfort — order your regular size
Fit for Plus Sizes & Curvier Figures
Bonmarché is known for thoughtful touches that improve fit:
-
Higher waistlines to smooth midsections
-
Longer hemlines for better coverage
-
Stretch inserts in trousers and dresses
-
Darts and panelling to flatter curves without cling
If you're between sizes or petite with curves, Bonmarché offers generous shaping without excess fabric — but don’t rely on guesswork.
Why Guessing Your Size Doesn’t Work — Even at Bonmarché
Although Bonmarché is known for consistency, body shapes vary — and so does the fit depending on:
-
Cut and silhouette
-
Bust/waist/hip proportions
-
Fabric stretch
-
Layering preference
That’s why the most reliable way to get it right is using your own body measurements.
