    Love it!

    I feel SO good in my swimsuit - it fits perfectly and gives me full-on mermaid vibes.

    Beautiful quality

    The long sleeved Monroe is a beautiful quality swimsuit. I ordered a larger size then usual to get the length as I am slightly long bodied! Once you get the knack of zipping up the back, this is easy to put on and also to get off. I have worn mine in an indoor pool as I like the extra coverage, but I also plan to wear it outdoors. The long sleeves are quite sheer so it doesn't feel too much like an old-style gym leotard. I love mine and I'm very happy to wear it.

    Lovely stylish swimsuit

    I’m an outdoor swimmer and this stylish long sleeved swimsuit is great for that purpose. It is stylish and flattering, the sheer inserts around the legs are particularly good. A little more stretch in the sleeves might make it even more comfortable (but it might be my fleshy arms!)

    Long sleeve Montoe

    I absolutely love this swimsuit- just did a 7 degree swim and it fooled my body into thinking it was a wetsuit ! Great support and comfort all round .

    Very nice swimsuit

    I have a cross back which I love but after wearing twice I realised that the bottom coverage was getting tricky when I swam so I sized up for this one- it’s a really nice swimsuit.
