Ordered these in 31p last year, prob could have worn a 30p, ordered 30p and 31p this year. the past couple of years the pilcro stet jeans in white fit me because they were cut straighter and not as curvy. this year neither size fit. 
this year the cut changed and it has a curvier fit. it's the waist that doesn't work for me. if you're curvier this is probably a good fit change.
