Are they worth it?
I'm 5'7, size 10-12 with a round bum, it's where I carry my weight and so far it's still perky which is very lucky and I want to make the most of it as long as I can 
Legs would be a 10 - in bottoms I buy a 12 to accommodate the aforementioned arse.
What size would you suggest I get?
Do they really not fade / ladder?
I want to believe the hype!
