Is it better to size up or down for sticky bra?

Choosing your true cup size provides the best starting point for sticky bra success, though the decision between sizing up or down depends on your specific goals and the bra's construction.

Most brands engineer their adhesive bras around true cup volume, but when you're between sizes, one-piece silicone styles perform better when sized up for maximum coverage and secure adhesion, while two-cup designs with center clasps allow you to size down slightly if you prioritize enhanced cleavage without spillage.

The construction fundamentally changes how the bra delivers support and coverage. Single silicone cups rely on surface area contact for stability, making true-to-size or larger the safer choice, while dual-cup styles with adjustable front closures offer more flexibility to customize your look.

Your individual breast shape, the outfit's neckline, and whether you need all-day security or temporary enhancement all influence the ideal fit, so start with your regular cup size and adjust based on how the specific style performs with proper application technique. Remember that adhesive bras function differently than traditional banded styles, so focus on achieving smooth edges, comfortable placement, and the coverage level that makes you feel confident and supported throughout your day.
