These pants are lovely. I've tried all three styles (Rosalind, Aimee and Cecilia) and Rosalind are definitely my favourite. Perfect fitting around my hips, no VPL, and the colours on the She Sells Sea Shells are really great. Even after several washes.
In shop bought pants I would wear a 12, but for these I wear a 10, so I agree with everyone who says go with your actual size, not your pants-adjusted size!
