    Essential Swimsuit Cobalt Size 16 Monroe

    Fab costume .I usually look for longer length costumes as I’m longer in the body.This costume is ok even on a 5 ft 9 curvier body.It feels great and looks good.Its my second Deakin and Blue costume and won’t be my last .They wear well .Have had my 1st costume for over 2 years and is still perfect on 2-3 swims a week.This one however is my new favourite .. for those days when you want a splash of colour and joy .

    My swimsuit

    A fabulous and comfortable swimsuit from a great independent brand. I bought the Monroe. I am 12-14 top and 16 bottom. It fits beautifully and will give me confidence on holiday and in the local pool. Highly recommended.

    Best Swimsuit I have found

    This swimsuit feels like a second skin. The fit is great and I can move without anything moving around. And what is even better, it looks fantastic.

    Excellent product

    I love my new swimsuit. It feels like robust material. It's a great shape and holds my bust in place well and isn't too revealing.
