To find your size, make sure you keep the measuring tape level all the way around your body.
Don't breathe in when measuring and don't pull the tape too tight, it needs to sit naturally. Wearing thin, tight clothing or underwear is recommended.
(If you don't have a measuring tape you could use some string or ribbon and then measure the lengths with a ruler)

Bust - Measure the widest part
Waist - Smallest part, in between your rib cage and hipbone 
Hips - Widest part around your bum. This may seem too low but its actually the correct way to measure your hips 

Sizing is just used as a basic guide, everyone's bodies are different. If you find you're in between sizing, you can add in your specific measurements in the optional custom section.  

Overall, the fabric is super stretchy so its pretty hard to go wrong! But please be mindful when selecting your size because I don't offer refunds as these bikinis are made to order specifically for YOU
