  • Description
    • The Diamond Geo t-back tankini top is a plus size swimwear top that’s made for getting active and adventuring this summer in comfort and style. You’ll love the modern print this plus size swimwear top features, in addition to the chic t-back design. 

      This plus size swimwear top is available in our new diamond geo print that features loud and deep rich colours in a chic spliced colour blocking design that features faded palm trees. You’ll love how modern this multi-coloured print is and how it looks flattering on every woman. Additionally, some of the main colours of this diamond geo print are teal, plum, blue, yellow and grey for a powerful summertime combo that can’t be missed out on. 

      This plus size swimsuit top has a v-neckline look with thick straps to frame your figure in style. This plus size swimsuit top’s bust is supported by a built-in shelf bra with moulded cups for a super supportive and sporty fit. This support holds your bust in place so you can get sporty, run, jump and play in the ocean waves, on the sand and every where in between. In addition, the cups are removable for a versatile style where you can change your support amount. The front of this plus size swimsuit top is sleek and loose-fitted so you stay comfortable and can move without feeling restricted. 

      The back of this plus size bathing suit top has a chic t-back style that’s made for summer. This design is super breathable, is ideal for water sports and will show off your back in style. After the t-back ends, the remainder of the plus size bathing suit top is consistent with the front’s loose-fitted and relaxed style. The bottom trim of this plus size swimsuit has a rounded bottom for a chic look. 

      Pair this plus size t-back tankini top with our plus size spliced high waisted pant for a go-to matching look that’s perfect for every beach day ahead. For additional coverage, pair with our sarong in plum, aqua or cobalt blue.

Looks great!

I haven’t worn it in the pool yet but it fits very well. I was a little concerned with no adjustable straps but thankfully it fits well that it’s not needed. I love how it flares out around the middle + bottom so it doesn’t cling to my hips. Lovely colourful print.

Size guide

All of our swimsuits are true to size. This means you should follow your normal sizing.

The best guide is your underwear - so what you would wear in a bra and undies is the size you order from us in tops and bottoms. For example, in you wear an 18E bra, you should order a size 18 swimsuit top from us.

If you are looking for a one piece and are in between sizes, say an 18E bra and a 20 in underpants, we recommend choosing the larger of the two sizes - so a size 20 in this case.

If you have any issues with your new swimsuit, we do 30 day refunds for full priced items and exchanges for all items - so you can swap to a size or style that is more suitable for you!
