Our Guide toswimwear sizing and fitting guide



A supportive, bra-sized fuller bust bikini, swimsuit or tankini will keep you feeling secure at the pool or on the beach, so you can run, jump and swim without any fear of spills - hooray! It can also give you more confidence when showing off your shape and allows us Bravissimo girls to have fun in the sun. But what size swimsuit should I buy(? This guide answers the questions we get asked most often.

What bikini size should I go for?

As a general rule we advise that you go for your usual bra size (we use UK bra sizes, if you need help converting your size from US to UK hopefully our Bra Sizing Explained page will help). Some women feel more comfortable going up a back size, because they find a looser band more comfortable for lounging and/or want to show off a smooth back (a snug fit can sometimes create lumps and bumps!). If you prefer to do this, remember to try a cup size smaller than you would normally wear in order to keep the same volume in the cup. For example, if you usually wear a 32G bra size but would like a looser fit on the back, you should try a 34FF. You do need to bear in mind that you will compromise on support if you go up a back size though – it’s your choice to make.

What size swimsuit should I buy? For example, what size is a 34 swimsuit?

As we’re all different in terms of our body shapes and height, you may need to try a couple of sizes to find the best fit for you. As a guide, a size 34 swimming costume is the equivalent to a US dress size 10. A size 32 swimsuit is a US dress size 8 and so on. If you’d like more room in the body of the swimsuit, try going up a back size and down a cup size (so that you keep the same volume in the cup). For example, if you usually wear a 32G bra size but think you’ll need more room in the body, you should try a 34FF.

I prefer to cover my tummy, what options do I have?

Other than a swimsuit, a tankini can be a brilliant option for lots of reasons. They obviously provide you with more coverage than a bikini, but they are a more versatile as you can pull them up or down to show as little or as much as your tummy as you like. They can also be easier to get on and off quickly. We tend to show our tankinis with a little gap between the top and the bottoms to show that it is a two-piece, rather than a swimsuit, but they are usually long enough to completely cover your tummy if that’s what you prefer.

What options are there for bikini bottoms?

Classic bikini brief shapes and tie-sides offer less coverage, whereas high-waisted and folded style bottoms offer more tummy coverage. Short style bottoms can be a good choice if you’d like more coverage over your hips. We have lots of options which offer more and less coverage depending on what you prefer.
