British Prep Meets Casual Cool

Jack Wills has long been a favourite of the UK high street. Known for its classic British prep style—think rugby shirts, cable knits, hoodies, and tailored outerwear—it has evolved into a go-to for smart casualwear across genders. But as fashion buyers know, brand identity doesn’t always equate to sizing clarity. So, does Jack Wills run big or small, and how does it compare to your usual brands?

🎯 At Tellar.co.uk, we’ve analysed every single brand’s size data—including Jack Wills—and match it perfectly to your body or known brand size. One-time quick set-up, always free to use, and you’ll never need to check a size chart again. You can even get a free tape measure. Access your best size across 1,500+ brands any time—no catches, no confusion.


Jack Wills Sizing at a Glance

Jack Wills generally runs true to size for most categories, with a tendency to feel slightly roomier in casual fits like hoodies, sweatpants and tees, while tailored garments such as jackets or structured shirts lean toward a snugger fit.

They use UK sizing across the board, and while consistency is better than many fast fashion competitors, you’ll still find variation by category—especially if you’re shopping across men’s and women’s lines.

Let’s break it down.

Why Jack Wills Sizing Confuses Shoppers

While Jack Wills maintains better consistency than many brands, shoppers still encounter size frustration due to:

  • Evolving fit trends: As the brand shifted from collegiate prep to a more trend-driven line, the cuts have changed subtly.

  • Variation in tailored vs casual lines: A size M hoodie is roomier than a size M formal shirt.

  • Different sizing tolerances across stores and outlets: Some Jack Wills collections are exclusive to retailers like ASOS or House of Fraser, which may use slightly altered blocks.

This is exactly why Tellar.co.uk was created—to eliminate this confusion. Whether you shop Jack Wills online or in-store, Tellar tells you your exact match in real time based on your body or current brand size.
