I ordered 3 cami tops at size 18. Delivery was prompt but all three are too tight.
I have for many years bought these type of tops from Elvi when there were shops and sections in department stores - I am still wearing some of them - and I have always bought size 18. It would not be any use buying size 20 instead as they are then too large around
the armholes ( I do not have an enormous bust size).
I am very disappointed and have returned all 3.
