Minimalist Streetwear with a Statement — But What Size Should You Buy?
Sisters & Seekers has quickly built a cult following for its clean branding, neutral tones, oversized silhouettes and unapologetic messaging. Based in the UK, this female-founded label specialises in limited-edition drops of sweats, co-ords, slogan-heavy basics, and elevated essentials that sell out fast.
But with a mix of unisex styles and oversized fits, many shoppers wonder:
What size am I in Sisters & Seekers? Do their sweatshirts and joggers run big or small?

Does Sisters & Seekers Run Big or Small?
Sisters & Seekers follows UK sizing, but many of their core pieces — especially sweatshirts, joggers, and outerwear — are oversized by design. This means:
-
Most tops and loungewear styles run large for a relaxed fit
-
Bottoms like joggers are generally true to size at the waist, with a looser leg
-
Fitted items like tank tops or crop tees run true to size or slightly small, depending on fabric
💡 If you prefer a standard or close-to-body fit, consider sizing down in their oversized collections.
