🏋️ Fit Tips
-
In-between sizes? Go up a size for more comfort, or down for a more compressive fit.
-
Our leggings are true to size with a supportive, sculpting feel.
-
Sports bras and tops may feel snug at first — they’re made to support you through every move.
- Compression outfits will be smaller in size when compared to the above tables as they're designed to be tight fitting.
🧼 Fabric & Fit Info
All HappilyFit pieces are made with flexible, sweat-wicking fabrics designed to stretch and move with your body. They may feel firm when first worn, but will mold to your shape after a few wears.
