Rated 4 out of 5 by from it fits Well , I was quite surprised tbh as when I shop outside my usual brand, I never fit into the bikini top which is a big struggle for me. I'm either a 40f or 38g. As 40f wasn't a option for me on here, I decided to take the plunge and purchase the 38g. Its does fit , would have been nicer if the band was a little looser, but overall it FITS BEAUTIFULLY and the look is stunning. The colour green is exactly what I was looking for. As for the bottoms, i purchased my usual size. It covers my mum tum and doesn't over show. Overall, happy with my purchase. I did have a discount code which I used, as the price of the bikini top is little overpriced. Only downside because of the wire and shape, item cannot be folded and I'm guessing I'll be hand washing the top by hand, not by washing machine. Not really a issue
