What is a Sports Bra?
A sports bra restricts breast movement during physical activity using either compression (smashing the breasts toward the chest) or encapsulation (separate cups for each breast).
Who is a Sports Bra Best For?
This style works best for workouts, running, yoga. Recommended size range: all sizes — D+ should choose encapsulation.
How to Make Sure Your Sports Bra Fits
- Two fingers should slide under the band — no more
- No spillage at top or under arms
- Straps should not dig in
- Replace every 6–12 months as elastic stretches
How to Size a Sports Bra
Use your everyday bra band and cup measurement as the starting point. Sports bras can be cup+band sized OR S/M/L. For S/M/L, use the brand chart.
Best Bras of This Type
- Wacoal — premium fit, runs true to size.
- ThirdLove — half-cup sizes for in-between fits.
- Panache / Freya — full-bust D–K options.
- Aerie / Lively — comfortable, affordable everyday fits.
Common Issues with Sports Bras
- Band too loose — sister-size down for tighter support.
- Cup gap at top — sister-size up or try a fuller-cup version.
- Straps slip — adjust shorter or use a racerback converter.
- Band rolls — fabric is too thin or sized too big.
