Sizing Guide
Find Your Perfect Fit
For the most accurate fit, we recommend measuring your underbust and using this to select your size from the chart below.
Our bras are designed to provide support through a firm, secure band, so this measurement is key to getting the right fit.
If you’re between sizes, your choice will come down to preference — a firmer, more compressive feel or a slightly more relaxed fit.
If you need a hand, our team is always here to help 💌: hello@kissactive.com
