Does Sweaty Betty Fit True to Size?

Generally, Sweaty Betty runs true to size, but with some key differences depending on fabric and style:

Leggings (Power, Zero Gravity, Super Sculpt):

Power: true to size, compressive but stretchy

Zero Gravity: snug and sculpting — may feel tight, especially in thighs

Super Sculpt: highly compressive — some prefer to size up

Tops and Vests: Slightly fitted, may require sizing up if you prefer a relaxed fit

Bras: Supportive, but tight-fitting — ideal size depends on bust-to-underband ratio

Sweaty Betty uses UK sizing, but compression level can impact comfort
