Hip: the widest part of your hips making sure the tape measure is even over your bum
Waist: your natural waistline above your belly button and below your rib cage
Bust: the fullest part of your bust at nipple level

Bathers
"They would have to be the most comfortable bathers I have ever worn. The straps stay in place doing aqua aerobics and the bathers don’t ride up."
Love it!
"Great boob coverage to play with the kids in the surf, holds the tummy in without being suffocating and just the right amount of bum coverage."
Great fit
"Super comfortable, easy to put on over my curvy bits and love the wide shoulder straps. The inbuilt bra even handles my buxom girlies quite well."

"Omg so flattering! The colour! The fit! I love the skinny straps and the shelf bra without the padding which always retains water! The material is gorgeous - not clingy at all! Slightly higher cut in the front than Im used to but not so much that it shows off too much. Definitely recommend!!"
"Bought two of these swimsuits in the $50 sale and already want more. Great fit for F cups! And high quality & sucky inny in all the right places. The bottom is slightly cheeky but I don’t mind as most swimsuits have too much coverage in that area. Love the ribbed texture fabric instead of the plain smooth. Just adds another element."
"I hate buying new swimsuits as I’m 74 and conscious that my body is no longer in the best of shape, but after reading the positive reviews from ladies of varying shapes and sizes, I ordered the Coolum Core Support One Piece. I am a size 12-14, so ordered the Large size and I am delighted to say the swimsuit fits perfectly and is very flattering. I havent washed now ordered the sarong to match."
"I was a bit worried about this swimsuit as it didn’t have as big a cup range as the Coolum in the bust but I preferred the thicker straps… And I am glad I read the approve reviews and got it anyway. It fits really well, even with a larger bust. Very flattering cut and beautiful material!"
"I absolutely love the colour, style and fabrication of this swimwear. First time buyer and very impressed. I bought mine on sale. No concerns with my next purchase as this is a high quality product. I have a little tummy now that I am 60 but this swimsuit is extremely flattering!"
"I absolutely love my new cossie. The colour, cut and quality of the fabric are all outstanding and I will definitely be adding a few more to my beach wardrobe for this Summer. The fit is perfect- very flattering and not too high cut or skimpy. I got a medium but as I’m small chested, a small would’ve bee ok as well. Super comfy regardless !"
"I stumbled across this brand on social media, saw a bunch of my friends follow this brand and thought I’d purchase a new one-piece. Blown away! The quality is beautiful, supports in all the right places and actually covers my bottom! (I’m not the cheeky bottom kind lol). Will definitely purchase again. Love them!"
"Absolutely love this swimsuit! The fit is incredibly flattering, with just the right amount of support to make you feel comfortable and confident. The ruching around the tummy is particularly flattering, and the colour is even more beautiful in person. It’s stylish, comfortable and makes me feel fabulous. Highly recommend!"
"The style is very flattering to the bust and I love how it sucks the wobbly tummy in without being tight. The colours and fabric are stunning. I am self concious about showing bum cheek, so I would like more coverage in that area. The rest fitted perfectly. I am inbetween sizes so I sized down as advised on the website, and definately needed to."
"I bought my true size, and they fit excellent. I agree with recommendation on website to size down as they are generous and do give a little. I love them. Have literally bought multiple pair for myself and as gifts for my sisters and best girlfriends. I love a bargain and picking up my size and chosen colours at $50 each & with a free gift has been awesome for me. Love love love it."
