SIZE CHART AND FIT GUIDE 

At NAIA we believe fit never goes out of fashion, that is why we fit all of our swim and resort wear a minimum of 5 times until it fits perfectly.  Here are few helpful tips to assist you while buying your perfect NAIA piece.  

  •  Our collection fits true to size. However if the individual product has any specific size information please adhere to the recommendations. For specific advice please either email contact@naiabeach.com or use the chat function.

  • Bikini tops and bottoms are sold separately, you can mix and match to find the best size and look for you. 

  • Some styles feature our Trademark 'Subtle Sculpt' offering comfortable stomach control. 

  • Different styles offer different amounts of coverage, bear this is mind when making your choice. 

  • Some styles have removable pads, others built in cups and hidden shelves for support. 

  • All sizing is shown in UK sizing please refer to the International size chart for conversions. 

  • If you are in-between sizes, we recommend sizing up in all of our styles. 

If you do have any questions, please contact our fit experts on the online chat function who simply love talking swim and will be happy to help.
