I weigh about 100 Lbs. so I think I should buy a size 4 in jeans? I do it online, so am hoping that is about right? Any thoughts?
Is this your first time buying jeans at your current weight? Unless you are very short, I imagine you would wear the smallest possible size. Take some rough measurements and read reviews.
I'm 5'4 and 115 pounds, no butt, no gut and can wear a 2 or 4 petite in pants depending on the cut and whatever random size was slapped on there. I do have some size 2 shorts and pants that are too big, but I also have 4s that fit perfectly. I have never actually tried on a 0 in anything because that's ridiculous. I wore a 6 or 8 the last time I was this weight (probably 12 or 15 years ago).
