Size 12 Swimwear

At Curvy Swimwear we understand that no two size 12 bodies are the same. With this is mind we ensure that our collections have a variety of styles available in size 12 to fit different silhouettes. Our size 12 swimwear is available in multifit styles with supportive shelf bras or with underwire inserts to fit and support your specific bust size. 

Our size 12 collection includes bikinis, tankini tops, one piece swimsuits, and swim dresses. You can also shop for size 12 swim separates with bikini bottoms and rash vests available to complete your look. You'll be spoilt for choice with our selection of stunning plain colours and gorgeous seasonal prints. 

Best Swimsuits for Size 12

The best swimsuit for a size 12 is the one that looks and feels good for you and your body. If you have a large bust that needs extra support, an underwire style might be the best for you. If you are size 12 and feel self conscious about your belly, a style with ruffles or a dress overlay will help you feel confident. 

If you have a bold personality and like to express yourself through fashion, the best swimsuit for you will be bright, colorful, and unique. Whereas a black or neutral colour in a classic swimsuit shape will be best for someone who prefers understated elegance and a timeless look. 

Size 12 One Piece Swimsuits

One piece swimsuits are what we do best. We stock brands that specialise in the best one piece styles to fit and flatter every shape and size. From strapless, long sleeved, underwire, tummy control, and sexy styles, we have a size 12 one piece to suit you. Take your time to consider what features will work best for you and enjoy browsing the extensive collection of size 12 one piece bathers available here at Curvy Swimwear.
