i like scrub tops that have some shape to them. the cheapest ones make a person look square like sponge bob. i like the ones that have a cut that fits, and not just because some strings were added to tie it behind your back to create a sort of waist.
scrub bottoms with a tie on the waist always feel sloppy to me, like they are falling off. and the ones with the big pockets on the sides of the thighs make a person look bottom heavy. i like the ones that have an elastic waist, pockets where pockets should be like on jeans, and a straight leg cut. this gives a person some shape to the bottom half as well.
in other words, get as far away from pajamas as you can get, and i will like them better.
