I am 5'4, 148 lbs with muscular legs and a smaller waist, i usually wear an 8 or 27 in jeans, but i decided to go with a 9 in these and they fit perfectly! These are the softest jeans ever and they are so comfortable. Adorable to style too.
They are VERY long though, so im usually having to wear 4-5 inch heels whenever i wear them so that i don't mess up the bottoms. I can't wait to buy all their other jeans though!
