South Beach Size Guide: Find Your Perfect Fit & What’s Worth Buying
Author: Stylist at TellarDate: 2025
Love South Beach’s bold swimwear, activewear, and loungewear—but not sure which size to go for? You’re not alone. Known for fun, feminine cuts and standout prints, South Beach offers fashion-led pieces for confident women—but like many fast-fashion brands, sizing can be inconsistent across categories.
At tellar.co.uk, we match your body measurements to the right size in over 1,500 brands, including South Beach. This guide explores how South Beach fits, how to find your perfect size, and what pieces are worth your money.
Who Are South Beach?
Founded in Manchester, South Beach is a UK-based label specialising in affordable swimwear, activewear, and loungewear that channels effortless cool. Their collections offer:
Statement bikinis, one-pieces & beachwear
On-trend co-ords, joggers, and lounge sets
Lightweight yoga and fitnesswear
Affordable accessories and footwear
South Beach regularly releases new drops, which means you’ll always find seasonal, Instagram-ready looks. But between changing cuts and factories, sizing is hard to predict—so don’t just rely on a tag. Use Tellar’s sizing tool for accurate, real-time results based on your body.
Does South Beach Run Small or Large?
Here’s what real shoppers say:
Swimwear runs small — especially bottoms and one-pieces
Loungewear fits true to size, but can shrink after washing
Activewear may run tight—aimed at compressive fit
No consistent fit rule across all categories
Some customers find they’re a size 8 in joggers but need a 12 in swimsuits. That’s where Tellar.co.uk eliminates the guesswork.
