Diamond Geo Long Sleeve Zip Up One Piece

The diamond geo zip front one piece is a gorgeous plus size one piece made for summer adventures under the sun.

This swimsuit is designed to be worn in salt water, fresh water, or home pools – not in heavy chlorine. If you intend to wear your swimsuit in public pools or hot spas, please shop our chlorine resistant range!

The diamond geo zip front one piece is a gorgeous plus size one piece made for summer adventures under the sun. This plus size one piece offers a beautiful coloured print, a sporty design and plenty of support to make a comfortable and fashionable plus size swimwear to wear all day long this summer. 

This plus size swimsuit is available in our diamond geo print that has a combination of teal, blue, yellow and plum with aspects of white and grey. In addition to this colourful colour blocking, this print also has cool faded palm trees that pop through for a tropical vibe. 

The front of this plus size swimsuit has a rounded neckline with a black trim and a large front zipper. The zipper ends under the bust so you can adjust it to create any style neckline to suit your fashion and coverage needs. Additionally, underneath the zip is a wide band in solid black to contrast against the colours and highlight your waistline. The bust of this plus size swimsuit is supported by a built-in shelf bra with moulded cups to give your bust a gentle lift while providing light shape to enhance their natural appearance. 

Around the back is a sleek and fitted look that lets the print stand out as main focus. In addition, this plus size swimwear has long sleeves to help keep your arms away from the sun while on the water and they provide additional warmth for cooler beach days. The sleeves are comfortable to wear and can easily be rolled up for when you’re getting warm. 

The bottoms of this plus size zip front one piece are classic cut to provide a comfy wear that gives you plenty of flexibility in movement so you can run, jump and play without feeling restricted. To accessorise, pair with a sun hat and sunnies for a go-to look you’ll love!

LOVE these swimmers!

I'm so happy with my swimmers. Not normally an item I would order online... but they are perfect! The description online was spot on, they feel great and hide all the right bits making you feel more confident.I was concerned that there was no cup in the swimmer, but the little bra shelf lifts the girls up nicely. The fabric is great quality, and the delivery was speedy. Thank you!

Love this!

This one-piece is fabulous and had everything I was looking for - sun-safe sleeves, a high back, lots of colours - and looks modern chic! I love it.
