Sizing hush dress

[CatsCantFlyFast]

Hi, just wondered if anybody has the hush Victoria dress. They're out of stock in m and I'm trying to work out if it comes up big and whether a small would fit. By their size guide it would seem not but it looks quite stretchy (and I'm dieting next week 😀)

Ive got it, I'm 5.2 small frame but a Gg bust and have the small which is perfect, I find hush usually comes up quite big and the top of dress is roomy

Thank you
