Size Guide
Let's Get You the Right Fit at ISA

Finding the perfect fit is the first step to feeling confident and comfortable.That's why we've created an easy-to-follow size guide just for you!
💡Step 1: Measure your under bust
Wrap a soft measuring tape around your ribcage, just under your bust.
Make sure it's snug but not too tight.
💡Step 2: Measure your over bust
measure around the fullest part of your bust while keeping the tape level and relaxed.
💡Step 3: Use the chart to find your band and cup size based on your measurements.
*The difference between your bust and underbust tells you your cup size.
*Your underbust measurement determines your band size.
❤️Tip: lf you have lower or fuller breasts, we recommend sizing up for a comfortable fit.
