They do have size charts, but I don't like to rely on them, I think I'm funny sizing since having kids. I can fit into some things in one size and not other things. So annoying. I will have to check their returns policies.
But I just asked DH if we had some spare cash and he said I can't buy online I have to try it on....so I have 2 outfits I can wear out of the house, one being maternity stuff still which doesn't fit me properly (not being pg anymore and all!) I have had for ever. Grrrr...I can't just buy stuff either cause I don't know if we do have any spare cash. And I have spent my own fortnightly allowance on the kids. Stupid me. So depressing.
