SUN68 Size Guide: What Size Am I in SUN68? Fit Advice & UK Sizing Help

With its casual energy, retro sportwear influence and subtle branding, SUN68 has become a staple for those who want to look effortlessly cool without chasing trends. Best known for iconic polos, logo knitwear, and elevated basics, the Italian brand is a favourite for smart-casual dressers who love off-duty style done right. But when it comes to sizing, many UK shoppers wonder:

What size am I in SUN68, and does it run big or small?

✨ Tellar.co.uk helps you find your perfect size in thousands of brands, including SUN68. You’ll get a free measuring tape, set up your profile once, and instantly receive accurate sizing recommendations tailored to your body shape, height, and garment type. Always free. No guesswork. No charts.

About SUN68: Easy Fashion with Italian DNA

Founded in Italy, SUN68 was born from a desire to create everyday clothing that feels simple, accessible, and stylish without trying too hard. Today, it’s stocked in designer boutiques across Europe and popular on sites like Yoox, Zalando, and Farfetch.

What makes it stand out:

Slim-fit polo shirts with minimal logos

Retro-inspired knitwear and sweatshirts

Classic chinos, jeans, and outerwear

Preppy but relaxed silhouettes

Despite its effortless appeal, SUN68 uses EU sizing—and its slim Italian tailoring can sometimes catch UK shoppers off guard.

So—Does SUN68 Run Big or Small?

SUN68 generally runs true to size, but most pieces have a slim, European fit—especially polos, shirts, and trousers. Knitwear and sweatshirts offer more room, while outerwear is often cut for a neat, tailored silhouette.

Fit Summary:

Polos & tees – slim fit, size up for relaxed feel

Knitwear – regular or slightly fitted

Trousers & jeans – tailored in waist, structured in thigh

Outerwear – true to size, slightly snug if layering

Womenswear – relaxed tops, fitted skirts or trousers

📏 Check your SUN68 size now using Tellar’s Store Size Lookup tool. It calculates your ideal size based on bust, chest, waist, hip, height and more—for each garment type.

Why SUN68 Sizing Can Be Misleading

SUN68’s minimalist design often hides structural tailoring, and many UK shoppers assume a looser fit than the brand delivers. Common sizing frustrations include:

Polos feeling tight in the arms or shoulder

Trousers with slim, structured thighs

Knits that look oversized online but arrive more tailored

Unclear measurements on reseller or marketplace product pages

That’s why Tellar.co.uk is your go-to sizing solution—it factors in the exact garment cut, fabric behaviour and your measurements to recommend the perfect size.
