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 fitexpert@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 fitexpert@naiabeach.com who simply love talking swim and will be happy to help.
