The Complete UK Guide to Women’s Jacket Sizes: Find Your Ideal Fit

Womens Leather Jacket

Finding the perfect jacket isn’t just about style – it’s about the fit. Whether you’re layering up for chilly British winters or adding a sleek leather jacket to your outfit, understanding women’s jacket sizes in the UK can make all the difference.

At Saint G UK, we know that a jacket should feel as good as it looks. Here’s your complete guide to women’s jacket sizes in the UK, with expert tips to help you find your ideal fit every time.

Why Jacket Sizing Matters

A well-fitted jacket doesn’t just flatter your shape – it enhances comfort, movement, and confidence.
Too tight, and it restricts; too loose, and it loses its shape. The right size ensures:

  • Proper shoulder alignment

  • Comfortable layering space

  • A polished, tailored silhouette

In the UK, jacket sizes can vary depending on brand, fabric, and cut, so knowing how to measure yourself correctly is the first step to effortless style.

Tip: Always check the brand’s specific size chart. Luxury and designer labels like Saint G UK may have tailored fits that differ slightly from high-street sizes.

How to Measure Yourself for the Perfect Fit

Before ordering online or visiting a store, grab a measuring tape and take three key measurements:

  1. Bust: Measure around the fullest part of your chest, keeping the tape level.

  2. Waist: Measure around the natural curve of your waistline.

  3. Hips: Measure around the widest part of your hips.

Pro Tip: Measure while wearing a light layer – this gives you a realistic fit for jackets worn over tops or dresses.

Fit Guide: Choosing the Right Jacket Type for Your Body Shape

Each jacket style sits differently on the body. Knowing which silhouettes complement your shape helps you find the most flattering fit:

  • Leather Jackets: Best fitted snugly around shoulders and chest. Saint G’s handcrafted leather jackets are designed to soften and mould with wear.

  • Bomber Jackets: Ideal for rectangle or athletic body shapes; they add structure and a defined waistline.

  • Blazers: Great for formal and smart-casual looks – ensure they sit neatly across the shoulders without pulling.

  • Puffer Jackets: Choose one that allows comfortable movement, especially if layering sweaters underneath.

  • Trench Coat: Works well for most body types, offering a straight, clean fall that creates a balanced outline.
