what are JoJo Maman Bebe sizes like?

Looking advise from anyone who has previously bought maternity clothes from JoJo Maman Bebe. I'm looking at buying the below coat & would normal be a pre-pregnancy size 8.

In other maternity stores I'm the following sizes:
Topshop tops - 8
Topshop leggings & jeans - 10 (to fit bump, but are loose round bum & legs)
New Look tops - 8
Dorothy Perkins tops - 8
h&M leggings - Small
JoJo Maman swimsuit - Small

My hips under bump are 37" & chest is 34".

This coat is sized 8, 10, 12 etc... So looking at my sizes - would you recommend going for an 8 or 10 ??

I don't have any experience with jojo coats but I always size up in coats to allow room for jumpers etc underneath! So I would go 10
