Baukjen clothes - how do sizes come up?

[minimuffin]

I was going to order a dress and some trousers from Baukjen - how are their sizes? I would say I'm a 12, but v straight up and down so I have to buy a 10 from some places. It's free delivery and returns so I should really order both sizes to try on, but it's more than I'd normally spend on a frock anyway so I'm baulking at putting double the amount on my card. Can anyone help? Thanks in advance!

Really random I'm afraid. Some stuff massive, some stuff small. I've bought, for example, in the same order two tops which were the same size and both went back, one swamped me, one I could hardly get on.
Check the online reviews for the specific garments, would be my advice.

Oh god, great... thanks horse. There are no reviews mentioning size. Might have to take a deep breath and buy 2! Really winds me up how UK sizing is pretty meaningless
