Good For Nothing Size Guide: What Size Am I in Good For Nothing? Fit Advice & UK Sizing Help

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.

Category	Fit Overview
T-Shirts	Slim fit with narrow sleeves – size up if you prefer a regular fit
Tracksuits	Tailored joggers and hoodies – true to size but close to the body
Cargo Pants	Tapered fit with a snug waist – size up for comfort
Shorts	Mid-thigh length, slim fit – stick to your size or go up for extra space
Womenswear	True to size – figure-hugging dresses and cropped tops

If you're in-between sizes or prefer a looser fit, size up, especially in tops and activewear-style pieces.

“Great fit for the gym — I love how it sits on the shoulders.”
“Joggers are spot on but don’t expect a loose fit.”
