    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.

    Cobalt monroe

    LOVE my cobalt blue monroe. Fits very well and keeps my core warm during my cold water swims

    I tried on lots of swimsuits and D&B’s were by far the best quality with exceptional customer service. I wish I’d asked for advice on sizing, and wriggled a bit more whilst trying this on! I think I’m quite long in the body and have discovered in action that I don’t have as much rear coverage as I would have liked!
