It's not quite as hot here in the Midwest as I'm used to (I'm from the DC region), low 90s, which isn't really *too* bad. It's definitely hot enough to sap your energy, though! I went out today to take my little girl to try to ride her new bike for the first time, and all of us were wilting within a few minutes.
However. Even though it's hot, I've had to add something to my attire that makes me hotter. What? Suspenders. Yes, actual "I look like an 80-year-old man suspenders," because I'm 39 weeks pregnant, due pretty much any time, and I've gotten to the point where my stomach is just so round that my pants fall down every 5 seconds when I walk around. They do make me hot, and they make my bra strap try to slide off my shoulder, but honestly it's better than hitching my pants up constantly! So that's my hot weather gear.
In general, though, it's maternity t-shirts and jean shorts for me! Too hot for footwear, I go barefoot almost all the time, wearing open sandals when I absolutely have to put on shoes.
