High-Street & Designer Options | Fit Science | Best Brands

Plus-size fashion isn’t about hiding your shape—it’s about celebrating it with fabrics, silhouettes, and fits that honour your body. Whether you’re shopping UK high street or USA premium, the key to building your wardrobe is choosing the right pieces for your shape, from brands that respect sizing diversity.

In this guide:

Core styling & wardrobe advice
Top UK & US plus-size brands
Fit tips and tailoring
And how Tellar.co.uk, the UK’s leading sizing tool, removes guesswork across 1,500+ brands.

🧵 1. Essentials for a Plus-Size Wardrobe

Your wardrobe should include:

Structured blazers for layering and shape
Wrap dresses for adjustable waist definition
Wide-leg trousers to lengthen legs and balance curves
Midi skirts for versatility and movement
Tailored shirts that skim without clinging
Dark denim or straight-leg jeans for daily wear
Supportive underlayers to enhance fit and confidence

Fit is the foundation. The same UK 18 fits differently across brands like Zara, Reiss or M&S. That’s why Tellar exists—to show you what will actually fit your shape, before you buy.
