Remember, size is nothing but a number

Ladies, don’t get hung up on the size or the number. It’s just that a number, I personally can wear a size large to a size 3X depending on the brand and fit. The instant I started to ignore the number and just focussed on how the items fit and felt on my body my life and closet changed, honestly it was a game changer. So follow our fit notes in each product listing and our size guide below, we are here to help you get the best fit possible. If you are unsure of your size (which is most of us), please contact us for a personalized online fitting and let us help you find the right size and style for your unique and beautiful body shape. 

Below are the sizing charts for Aqua Bay Swim Co Brand Swimwear and can be used for most of the Womenswear brands we carry unless we state otherwise on the individual product page. If a specific product doesn’t follow the size chart below it will have fit information included on the product page for that item. Also when we reference true to size or size up or down, it’s in reference to this size chart. If in doubt, we are just an email or chat msg away and are always happy to assist with fit and sizing questions. 


All measurements are in inches, taken around the body using a soft measuring tape.

How to measure to get the perfect fit for your bathing suit, plus size swimwear canada, bikinis canada, d cup swimwear

Determining Cup Size

How, you ask, can one bathing suit accommodate a range of cup sizes? This is because of the smart design concept of the fully adjustable back which allows you to fit to your band measurement. A 36 H and a 40DD can be a same or similar cup/underwire. 

Take your bust measurement minus your underbust measurement, then take the difference and refer to the chart below. (Ex 40"-36"= 4" which is D cup) 




1" A
2" B
3" C
4" D
5" DD
6" F
7" G
8" H


NOTE - the cup sizes In our size chart are suggested for best fit based on fittings of many many women of all shapes and sizes, however,  it has been shown that women have been able to go outside of the suggested cup range by plus or minus one cup size. Also if you have a bust that is not as full or very full, the firm cups can be removed and allow more flexibility for smaller and fuller don’t fret we have you all covered! You don’t need the cup ladies, these tops are all double lined.
