What Our Customers Say
"I have looked everywhere for a bikini top to fit larger boobs, this is perfection. I was a little nervous buying this online from overseas, but I read the reviews and thought I'll give it a go. The quality and fit is amazing, very impressed and super comfy. I sized up in cup size as like another review said swim togs have a little less give and it's perfect. Will definitely be doing some more shopping here." — Sara R., New Zealand ⭐⭐⭐⭐⭐

Size Guide
Finding your perfect fit for your swimsuit is easy with Curvy Swimwear's size advice. Our swimwear brands are designed in Australia to standard Australian sizes. They are cut true to size, so you can confidently choose your regular size when shopping with us.
A helpful tip is to consider your underwear size as a guide. For instance, if you typically wear a bra size 18E, then you'll want to order a size 18 swimsuit from Curvy Swimwear.
If you happen to fall between sizes, such as wearing a bra size 18E but a 20 in underpants, we recommend opting for the larger size for optimal comfort and fit. In this scenario, selecting a size 20 swimsuit would be ideal.
Take note of any size tips as well as the suggested cup fitting for each swimsuit. Product notes may suggest going up a size if you are longer in the body or if you have a larger bust.
At Curvy Swimwear, we understand that finding the right fit is essential, which is why we offer a hassle-free return policy. You can return any unworn items, including sale items, as long as they are returned with their original tags and sanitary labels intact. .
Need assistance or fit advice? Our friendly team of experts is here to help during business hours. Simply reach out to us via our online chat, and we'll guide you in finding the perfect swimsuit for your curves.
Shop confidently with Curvy Swimwear and embrace your beach-ready look with the perfect fit.

FAQs
We suggest going with your normal bra and undies size. In between sizes? Size up! Nothings worse than tight swimmers.
Ordering a one piece? Go with the bigger size between your top and bottom (e.g. if you're a 18 on top, but a 20 in bottoms, order a size 20 in a one piece!)
If you spend over $99.95 and purchase before midday, we express post your package same day for free!
We're known to be quite speedy, so depending on the post, you can expect your swimwear to arrive in a few days.
No, because we sell out too quickly to accept exchanges!
Instead, send back your package using the form included in your order and order the new swimsuit from our website.
Once we receive your returned parcel, we process your return payment the same day!
