Infinity Leather Sizing: What UK Shoppers Need to Know

Tailored Fit, Not Oversized

Infinity Leather designs are rooted in classic British tailoring with a modern twist. That means their jackets, coats and bombers are often structured, close-fitting, and designed to hug the body. They’re not oversized like streetwear labels nor slouchy like many fast fashion brands.

For most people, Infinity Leather runs true to size—but on the snug side. This is especially true for:

  • Fitted biker jackets

  • Tailored bombers

  • Slimline leather blazers

🧥 Because leather doesn’t stretch much over time, getting the right fit first time is critical—you don’t want something too tight, but too loose will ruin the silhouette. Tellar.co.uk removes all guesswork with instant brand-fit matching.


Common Fit Issues With Leather Jackets (and How to Avoid Them)

Tellar's user feedback has revealed common sizing complaints about leather jackets, especially when shopping online from UK-based brands like Infinity Leather, AllSaints, or Gerry Weber:

  • Shoulders too tight

  • Chest or bust restricted when zipped

  • Sleeves slightly long or stiff

  • Waist too loose compared to bust

Infinity Leather uses real leather, which doesn't mould like stretch fabrics. So unlike brands such as Eileen Fisher or FatFace, there’s very little give in the material.

🎯 That’s why Tellar.co.uk is built to help you get it right—once you enter your measurements, you’ll never have to check a chart again.

What Items Are Worth Buying from Infinity Leather?

Infinity Leather’s appeal lies in its mix of heritage styling and premium materials. If you’re unsure where to begin, these pieces are our top picks:

1. Classic Biker Jacket

This is the brand’s signature product—made from lambskin or cowhide, with silver-tone zips and a sculpted waist. Perfect for off-duty style. Expect a snug fit. Use Tellar.co.uk to ensure it hugs in the right places, not the wrong ones.

2. Vintage Leather Bomber

Infinity’s bomber jackets are built with slightly more room in the chest and arms, making them ideal for casual layering. This is the one to buy if you don’t like super-fitted silhouettes.

3. Tailored Leather Blazer

The modern leather blazer is a statement piece that bridges the gap between smart and edgy. Infinity’s version is close-fitting, so use Tellar to verify the waist and bust allowances before ordering.

4. Shearling-Lined Coats

For winter, the brand’s shearling and aviator coats are outstanding. These pieces are warmer, heavier, and a little more forgiving—but they’re still structured. Sizing up for winter layering is recommended unless you prefer a minimalist fit.


Why Leather Fit Is So Important (And So Hard to Get Right)

Unlike denim or cotton, leather has almost no flexibility. That means even 1cm off on your chest or shoulders can result in discomfort—or worse, an unwearable piece.

Yet every leather brand cuts differently:

  • Infinity Leather = tailored and slim

  • AllSaints = slightly oversized

  • Belstaff = true-to-size with military fit

  • Boda Skins = ultra-tight fit

This is why Tellar is so powerful—it’s not just a size converter, it’s a size matcher. It takes your actual measurements and compares them against each brand’s real sizing data, so you always get your best-fitting size.
