What’s My Clothes Size at Banana Republic? Does Banana Republic Run Big or Small?

Banana Republic is a global fashion brand known for its polished staples, tailored silhouettes, and refined workwear. As part of the Gap Inc. family, Banana Republic leans toward elevated essentials—from blazers and high-rise trousers to fluid dresses and luxury knitwear. With clean lines and a timeless aesthetic, it’s a go-to for shoppers who want versatile, grown-up style.

But there’s a recurring question for UK shoppers:

Does Banana Republic run big or small?

And how can you make sure you're ordering the right size when shopping online from the UK?

This post explains Banana Republic’s sizing in detail—and introduces Tellar.co.uk, the UK’s most accurate free sizing tool that calculates your exact Banana Republic size in real time, based on your shape, proportions, and the garment structure.

Does Banana Republic Run Big or Small?

Banana Republic typically runs true to size or slightly large, especially in:

Blouses and knitwear
Outerwear and oversized shirts
Relaxed dresses

That said, structured trousers, fitted blazers, and button-up dresses can run snug at the waist, hip or bust, particularly if made from non-stretch fabrics.

If you're between sizes or prefer a fitted look:

Size down in tops, tees and knitwear
Size up in tailored trousers, bodycon dresses, or structured shirts

Why Banana Republic Sizing Varies

1. American Fit Block

Like GAP, Banana Republic uses a US fit model, which typically assumes:

Slightly longer torso
More room through the body
Comfort-based ease in casual garments

This means some pieces may feel generous compared to standard UK fits.

2. Fabric and Fit Diversity

Banana Republic uses a wide range of high-quality fabrics:

Wool and tweed for tailoring
Viscose, silk and TENCEL™ for dresses and blouses
Stretch cotton and ponte jersey for trousers and suits

Fit depends heavily on whether the garment has stretch and how it's cut.

3. Design Intent

Some garments are intentionally oversized, while others (e.g. pencil skirts, sheath dresses) are structured and precise. Product descriptions don’t always clarify this—so sizing becomes guesswork.

Banana Republic uses US numerical sizing, so UK shoppers need to convert carefully. But even after converting, this doesn’t account for:

Garment cut
Fabric type
Your body shape and proportions

That’s where Tellar.co.uk helps.
