I don’t know if anyone else has had this issue but it is frustrating. I will buy two of the same things but in different colors and they will fit like two different sizes. I bought the Wunder train Strappy bra in deep sea blue and in black ( both size 10 and both C/D cup) and the deep sea blue one fits like it’s a size smaller. This has happened to me other times also with other things from lulu too.
