Learn how to fit the Reggiseno Sportivo Principessa Sport for secure support. Step-by-step sizing, strap adjustment, and comfort checks for high-impact workouts.
Quick answer
Choose the Reggiseno Sportivo Principessa Sport in your usual band and cup size, then fine-tune the wide, adjustable straps for a secure, bounce-free fit. Always test the fit with a quick run or jump before committing to a workout.
Why the Principessa Sport suits high-impact training
The Reggiseno Sportivo Principessa Sport is built with a preformed, wire-free inner structure that wraps securely around the bust. This design delivers reliable support without the pressure points of underwires, making it a smart choice for running, boxing, and cardio sessions.
Its breathable fabric includes a sweat-resistant band under the bust, which helps manage moisture during intense exercise. Wide, adjustable straps can be crossed at the back for extra stability, especially useful when you need maximum hold.
When to size up or down
If you are between sizes, consider sizing up in the band if you prefer a less compressive feel, or down if you want a firmer, more locked-in fit. Keep in mind that the wire-free design may feel different from an underwired bra—give yourself a few minutes to adjust.
Remember that the Principessa Sport is designed for high-impact activities; a snug fit is essential for support, but it should never restrict breathing or cause chafing.
Step-by-step fit and support check
- Measure your underbust and bust: Use a soft tape measure to find your underbust (ribcage) and bust circumference. Choose the size that matches your measurements according to the size chart. Common mistake: measuring over clothing or pulling the tape too tight—wear a non-padded bra and keep the tape snug but level. Double-check that the tape is parallel to the floor for accurate sizing.
- Put on the bra and adjust the band: Fasten the bra on the loosest hook and adjust the band so it sits firmly around your ribcage, not riding up. The band should provide most of the support. Checkpoint: you should be able to slide two fingers under the band, but it shouldn't twist easily. If the band rides up, try a smaller band size.
- Position the cups and straps: Scoop your breast tissue into the cups to ensure the preformed structure wraps fully around the bust. Adjust the wide straps so they sit flat on your shoulders without digging in. For high-impact activities, cross the straps at the back for extra support. Common mistake: straps too loose, causing bounce, or too tight, causing shoulder pain. Crossed straps should feel secure but not restrict arm movement.
- Test the fit with movement: Jump up and down, run in place, or do a few arm circles. The bra should stay in place with minimal bounce, and the band should not shift. Check for any rubbing or pressure points, especially under the bust and along the straps. If you feel discomfort, readjust the straps or consider a different size. A good fit means you can move freely without constant readjustment.
- Check comfort during a workout: Wear the bra for a short workout session. The breathable fabric and sweat band should keep you dry, and the wire-free design should not poke or dig. If you experience chafing, ensure the band is smooth against your skin and consider applying anti-chafe balm. Common mistake: ignoring minor discomfort that can lead to irritation over time. After the workout, check for red marks that fade within 30 minutes—persistent marks mean the fit is too tight.
