Good For Nothing has made its mark on the UK fashion scene with bold prints, fitted cuts, and a streetwear-meets-gymwear aesthetic. Known for its butterfly logo, muscle-fit tees, and matching sets, it’s a go-to for shoppers who want statement pieces that hug the body — but its sizing can often leave people wondering:

  • “Does Good For Nothing run small or true to size?”

  • “What UK size should I order in their tracksuits or shirts?”

  • “Is it cut for gym bodies or standard builds?”

At Tellar.co.uk, we’ve analysed Good For Nothing’s entire product range and matched it against over 1,500+ brands to give UK customers accurate, data-driven sizing advice — personalised to your actual measurements.


Does Good For Nothing Run Small or True to Size?

Good For Nothing runs fitted by design, especially in men's T-shirts, hoodies, and shorts. Their garments are tailored for a slim or athletic silhouette — so expect close cuts and narrow sleeves.

Fit Overview

T-Shirts

Slim fit with narrow sleeves – size up if you prefer a regular fit

How to Measure Yourself for Good For Nothing

Since Good For Nothing cuts close to the body, it’s important to take accurate measurements — especially for tops and tracksuits.

Use a flexible tape measure and record the following:

  • Chest: Measure around the fullest part of your chest (men) or bust (women)

  • Waist: Wrap around your natural waistline (not too tight)

  • Hips: Measure around the widest point of your hips or bum

No tape measure? We’ll post one to you free when you create your Tellar.co.uk profile.

  • Jackets fit close to the arms and chest

  • Best for layering over one base layer — not bulky

3. Logo Shorts & Swim Sets

  • Shorts often have limited stretch

What Real Customers Say

We gathered verified customer feedback from ASOS, Footasylum, and Good For Nothing's official site:

“The T-shirt is quality, but it’s super tight. I usually wear a M and had to get an L.”

“Great fit for the gym — I love how it sits on the shoulders.”

“Joggers are spot on but don’t expect a loose fit.”

“I’m a UK 12 and the Large fit well, but very figure-hugging.”

This aligns with our data: Good For Nothing is designed to flatter a fitted silhouette. Go with your usual size if you like snug clothing — size up for a more relaxed fit.
