I'm also 5'2", and the bows on the wraps are whatever you make them to be. I knot mine, actually. Once wrapped, they sit down on your hip and are pretty well hidden under the belly.
In other words, they're not big at all. It'll look like a belt that you tied around your waist.
The sizes are true to what you wear now. I am a medium in most shirts pre-pregnancy. For the wrap tops, I have ordered a 3 and am fine with them. I do have one that is a 4, and mostly, it's that the fabric is longer to tie around your belly.
Seriously, I wear these clothes more than anything else I've got for maternity clothes. I have 4 wrap tops, the v-neck kimono (reversible) wrap top, the ruched kimono v-neck tee and then the garbo trousers. They are really my weekly rotation, and hold up impeccably to washing. And I've been wearing this stuff since before I was really showing. It's looked great the whole time, and accomodates me perfectly as I get bigger!
(I swear I'm not a spokesperson for IO...)
The only thing I don't like is the jeans. They don't fit me well because they are not elastic in the back, and the pockets on the back make my rear look big...and at this point, I don't need any help with that!
