I've used the Calculator and I'm not sure what size to choose

Anita McLachlan - 1st December 2021

So you've put your measurements into The Shape & Size Calculator and you've got different sizes coming up for your bust, waist and hips. Which size do you choose?

Great question and it's one that I can answer from the benefit of 12 years experience. Here's what I do when I use the Shape & Size Calculator to help women with their swimsuit selections.

1. Choose a 'mid range size'

  • for example if you are say a 20 bust, 24 waist and 22 hips - go for a 22.

2. Choose the most 'common' number

  • for example if you are an 18 bust, 20 waist and 18 hips - go for an 18.

BUT...and there is always a but girls....if you have a more than 2 size difference between bust and hips - so a 16 bust and 22 hips then you will need to consider a 2 piece (separates) like a Tankini Top and separate Bottom so that you can get the right fit for your top and your bottom. There are very few one pieces that will give you a great fit overall with such a size difference.

3. Consider what is going to need more support meaning, if you are going to go for a 22 and your measurements show that you have say a 20 bust then choose a cossie that has adjustable straps so that you can bring in that area to suit your shape and size without losing support in that area.
