I can't remember why, but I had two pairs of the same BR white jeans last year (straight leg), same size, and they were a drastically different fit. I almost got myself in trouble, as a friend was going to take my extra pair, and I almost gave her the pair that fit me well, without realizing. When she said "may as well take the ones that I tried on" I realized that _I_ should perhaps take the ones that I had tried on! Neither of us liked the second pair - they went back.
so, long story to say that if they are close, you might want to order a couple more pairs, as another pair might be perfect. And BR has 35-40% off every week it seems, so getting a sale price shouldn't be an issue.
