Size Guide

RAQ Sizing

At RAQ, we design bikinis with adjustability and flexibility in mind, so that our bikinis can work for multiple cup sizes and shapes. The material is so stretchy and adaptive that there is no need to offer every single bra size. It is for this reason that we have chosen to combine our cup sizes.

Hot tip: If you are looking for more cleavage, opt for the smaller cup size. 

Sister Sizes

Sister sizes are alternate sizes that surround your bra size where the cup volume remains the same, even though the band size and cup letter change. 

True size not available? If your true size is unavailable, you can try a sister size. Our bikini tops have three settings at the back, so you can adjust the band to make it fit better. It may fit just as well as your true bra size.

Fit not quite right? If you've ordered a bikini top and the cup fits but the band is too big or too small, you may find that a sister size is a better fit. The cup will be the same but the band will be tighter or looser.

Each cup size will have several sister sizes that may also work, just follow the examples below:

When reducing the band, go up in the cup. 
10D/DD is equivalent to 8E/F
16FF/G is equivalent to 14GG/H

 

When increasing the band, go down in the cup. 
12GG/H is equivalent to a 14FF/G
14E/F is equivalent to an 16D/DD
