Isabella Oliver the scoop maternity tshirt

[TKKW]

Hi, looking at some of these on ebay. I'm a 10 or small 12 - broad back, no bust. Not sure what size to go size for - 2 or 3?
Can anyone advise?
Thanks

I would get a 2. I have a dress and its on the big size, am size 10 and 31 weeks.

I have one of these in a 2 - I'm a good size 10 and it fits beautifully
