Bikini Size Chart, AUS

Wearing a well-fitting bikini will make you feel secure and comfortable on the beach. And it will also look great :) Let us help you determine you right Australian bikini size...

How to Measure Bikini Size

Measure Hips: Measure around your body (circumference) at the fullest part of the hips. You will find your hips approximately 7" to 9" below your waistline (there are som individual differences.) Make sure to keep the measuring tape parallel with floor.
Measure Waist: Measure circumference around your waistline. Not sure where you waistline is? Your waistline is the narrowest/slimmest part of your torso, and is usually located just above your belly button. Stand in front of a mirror, and bend to one side. Your waistline is simply where you can see a natural indentation in torso on this side.
Measure Bust: Measure over the fullest part of your bust. Keep measuring tape parallel with floor.

Use your measurements to determine your bikini size (bikini bottom and bikini top) with our Austalian bikini size charts below.

Australian Bikini Top Size

Bikini top sizes are given in three (3) different ways, depending on brand and model:

1. Bra Size is used. Then you pick bikini bottom size and bikini top size separately. See here to determine your Australian bra size. Size example: Bottom Size: 12/M, Top Size: 14C

2. Bikini top size is determined with the same size system as the bikini bottom, just by adding your bust measurement in addition to waist and hips measurements. Size example: Bikini Bottom: 12/M, Top Size: 12/M (if you can pick bottom size and top size separately) or Bikini Size: 12/M (if sized as a set). Use the bikini size chart below to determine your bikini top size.:

Size	Bust	Waist	Hips

XS (6)	84	64	92
S (8)	87	66	94
