Well, I guess I'll have to keep the blouse, as it rated a KILLER from Angie.
And Angie, you're right that the pants are tighter fitted through the thighs than they should be, and that they're not actually slouchy pants (they don't even slouch on the model: http://us.dorothyperkins.com/w.....ageSize=20 ). They just *feel* slouchier than most other pants I own.
Unfortunately, I'm not sure how likely I am to return any of this, because evidently one has to return via mail to the UK I thought they'd be like ASOS, which has a US based distributor to whom returns are mailed. I usually don't buy from retailers that don't have a good returns policy, and I hardly ever buy pants online, but the color, style, and price of the blush pants were just too good to pass up. And I guess, because the pants aren't actually that slouchy, they actually looked pretty good with untucked tops, at least to me. So I may keep them for that purpose, at least--especially since this week, I've been craving silky, non-skin tight pants since my hives returned and friction (from jeans, or rough polyesters) only exacerbates them.
