Neckline checks
Racerback tops draw the shoulder fabric inward. A conventional bra strap may show near the front or back even when most of the torso is covered. Start by checking the shoulder cut and then consider the neckline and back.
Choose your solutionCheck existing bra compatibility
If you have a bra designed for the shoulder shape and it stays covered, you may not need an adhesive bra. Pop can add lift inside a suitable existing bra, provided there is enough space in the cups.
Check adhesive-cup coverage
Pop Up can remove conventional shoulder straps from the outfit, but a narrow front panel or deep armhole may expose its cups. The absence of straps is only part of the fit check. Look at the side view and raise your arms before deciding.
Your fitting checklist
- Check front strap lines
- Look at the side opening
- Test the cutaway shoulders
