Uniqlo tee in size S. I have this tee in black and white (for the white color see my other recent post on LTK). It's the perfect cropped length if you're petite.
White shorts in size 2. I wonder if I need size 4 but am trying to get to a healthier weight. (Slowly losing visceral fat by watching my portions.)
I personally go down half a size in the 327 New Balance sneakers but a lot of people say they run true to size. I find they're very wide and roomy in the toe box.
Exact crossbody bag linked.
I'm 5' 2.5" and currently 117 pounds.
