Frequently Asked Questions
How do I measure myself correctly for a bikini?
Measure your bust at the fullest part while wearing a well-fitting bra. Measure underbust snugly under your breasts. Measure waist at the narrowest point and hips at the widest point. Keep the measuring tape parallel to the floor.
Do bikini sizes differ from regular bra sizes?
Yes, bikini sizes can differ from regular bras due to different materials, stretch, and support requirements. Swimwear is designed to provide support when wet and during movement in water.
What if I'm between sizes in bikinis?
For bikini tops, choose the smaller size for better support, especially if you'll be swimming actively. For bottoms, choose the larger size for comfort. Consider that wet swimwear may stretch.
Can I mix different sizes for top and bottom?
Absolutely! Many people need different sizes for tops and bottoms. Most brands sell separates, allowing you to choose the perfect fit for each piece.
How do international bikini sizes compare?
US sizes run 32-44 for bands, EU uses 70-105, UK mirrors EU but with different cup progressions, and AU sizing ranges from 8-24. Always check specific brand charts as they can vary.
What bikini style works best for my measurements?
Triangle tops work for smaller busts, underwire or molded cups for larger busts, high-waisted bottoms for longer torsos, and boy shorts for more coverage. Consider your activity level and comfort preferences.
