I really recommend you try them out! They can even measure you instore if you're unsure of your size.
I recently purchased this....
.... And fell in love with it! Will certainly be purchasing more. The fit and shape are exactly what I was looking for - sexy, cute and flattering for my size 14 and 36DD shape!
Note- I always buy underwear one size bigger than I am as I hate anything cutting in to me. Do you find this? Comment below! :) x
