Bodyline sizing info :)

[candy-gram.livejournal.com]

When the search engine proves fruitless and the Bodyline comm is all but dead, I hope it's not minded when I post my question here instead. I am curious about the sizing on 3 dresses, L412, L302, and L039.

I am curious how true they run to the sizes listed? Although I am within their max listed measurements (70cm waist, 87cm bust), I have received skirts from Bodyline before that supposedly went up to a 85cm waist and yet pinched into me like no other. I don't want to spend a decent amount on dresses that won't actually fit comfortably. Also, I'm interested if these dresses have zippers? Any help would be appreciated :) Thanks!
