I am starting nursing school in the fall and I will soon need to purchase my uniform, but I am clueless as to what size I should purchase! When the semester starts I will be ~26w and I am due right before Thanksgiving. Pre-pregnancy and currently, at 13w3d, I would be wearing a small top. The uniform company does not offer maternity sizing and it's just your standard adult XS-3X (S-3X for shirts).

The uniform we are required to purchase includes at least:
-2 white polo shirts with the schools logo
-2 pair of cargo scrub pants
-1 warm up jacket
-1 lab coat

Any suggestions? Should I purchase two sets of polo's in two different sizes (ex. 2 medium, 2 large)? I want the clothing to fit and look put together...I don't it to be huge, but I also don't want my bump hanging out. Thanks!
