    Love the design but not the most functional

    Love the design and look of the this top, but I think it is not great for larger busts. I originally ordered a large which was way too small, and then switched for the XXL and I have to tie it quite tight. Even though that is the size recommended for my cup size. I love it but have to be careful while wearing it that nothing slips out!

    My bad

    I should’ve sized up and based my order on a previous size where a large was gaping. However, with the tied back it’s easily adjustable for same. We shall see if I have my Janet Jackson moment 😅
