Guess is a globally recognised fashion brand known for its trend-led clothing, bold denim, and distinctive logo pieces. Whether you’re eyeing a pair of signature skinny jeans, a logo tee, or a structured blazer, understanding how Guess sizing works is key to avoiding a frustrating fit. In this guide, we break down the brand’s size consistency, how it varies between collections, and which items are worth investing in. Plus, we’ll show you how Tellar.co.uk can simplify your sizing decisions in seconds.
A Quick Brand Overview: The Guess Style Identity
Founded in 1981 in Los Angeles by the Marciano brothers, Guess built its reputation with iconic denim campaigns and glamorous Americana fashion. Over the years, the brand has expanded into accessories, watches, activewear, and even children's clothing. Its aesthetic blends modern sex appeal with a nostalgic twist – perfect for statement-making streetwear or casual elegance.
But with such a wide product range and international presence, how consistent is Guess sizing really?
So… Does Guess Run Big or Small?
Short answer: Guess typically runs small to true to size, depending on the collection and region.
Let’s look at the key points:
-
Women's Clothing: Guess is widely reported to run small, especially in form-fitting dresses, crop tops, and slim jeans. Many shoppers suggest sizing up if you're between sizes or curvier in the hips or bust.
-
Men’s Clothing: Guess menswear leans more true to size, especially in t-shirts, jackets, and trousers. However, some slim-fit items may feel tighter than UK high street standards.
-
Denim: A core category for Guess, denim sizing can vary. US-labelled jeans often run tighter than expected in UK sizes. Mid-rise and high-rise skinny fits tend to be snug at the waist and thighs.
👉 Bottom line: Guess sizing isn’t uniform across regions. Products labelled in US sizes are common on UK sites, so using your body measurements is the safest route.

Does Guess Offer Plus Sizes?
In the UK, Guess has limited availability for sizes above UK 14 for women or XXL for men. While its US website occasionally lists extended sizing (like XXL or 1X), these are rarely stocked on UK retail sites.

Best Items to Buy from Guess UK
While sizing may require some attention, Guess remains popular for its quality, finishes, and trend-forward cuts. Here are some of the best categories to shop:
1. Denim (Jeans and Jackets)
Guess is synonymous with denim. From high-rise skinnies to distressed jackets, their jeans often feature stretch blends for flexibility. Popular cuts include:
-
Power Skinny and 1981 Skinny for sleek silhouettes
-
Mom jeans and wide-leg for on-trend casualwear
-
Cropped jackets with logo detailing for layering
Use Tellar.co.uk to check how Guess denim fits you specifically based on your hip and waist size.
2. Logo Tees and Graphic Tops
These run small, so size up if you want a looser fit. They’re great for casual layering or styling under blazers. Expect high-quality cotton and bold prints.
3. Dresses
Particularly in bodycon or eveningwear styles, these are form-fitting and may run tight. Tall women may find short hemlines, so always check the length.
4. Blazers and Structured Jackets
These tend to be true to size with a polished finish – a great investment piece if you want tailored but contemporary.
5. Watches and Bags
Accessories don’t have sizing issues, but they do reflect the brand’s glamorous aesthetic – great if you want a timeless gift or finishing piece.

Why Size Consistency Matters (and Why Brands Like Guess Fall Short)
Fashion sizing remains an industry-wide issue. Guess isn’t alone in being inconsistent – even within their own product lines. Factors like:
-
Regional sizing (US vs EU vs UK)
-
Fit (skinny vs oversized)
-
Material (stretch vs rigid denim)
-
Gender targeting (men’s vs women’s fit standards)
...all affect the label on the tag.
