We try our best to keep sizes similar to the retail chains, such as Woolworths & H&M, so if you know your size there, we should be able to get your blushproof size.
Since these are period absorbing undies, a snug fit is best. 
To put your mind at ease though, we do offer a 45-day exchange, no questions asked. We want to make sure you get the best fit & size for your body.
