    Too too fabulous!

    I previously had issues with a couple of styles and sizing but am absolutely THRILLED with the Sweetheart swimsuit! I hadn't worn it until the middle of December when I went to Cape Town for a holiday. I love, love love this suit!

    Fab swimsuit

    Love the sweetheart swimsuit navy & plum so much that I had to buy another one after I wore mine for four years at least twice a week. Nothing tips the quality and feel of this. Just the best.

    Sweetheart Swimsuit

    This is the most comfortable costume I have ever had. The fit is very good. The style is wonderful and flattering. Has been worn in the sea several times now and is still looking good. I would definitely recommend deacon & blue to friends and family.
