White, Gray, and Black

Someone in the universe needs to explain something to me. Why is it that when I think I have worn enough layers to work, my classroom is freezing, proving me horribly wrong, but when I wear more layers, thinking my classroom will be freezing, my classroom feels like a sauna? Honestly, if my room had a gender, it would certainly check the "menopausal woman" box. This morning, I pulled together this outfit and loved the combination of neutrals. Could I wear my blazer past the late bell for first period? Nope. I sweat my way out of the blazer before I even gave my first set of students a warm-up (pun unintended).
I cannot believe my hair still looked presentable even though the patch testing on my back prevented me from showering since Monday morning. Oh, the things I admit to the internets.

(Forgive the painter's tape. This stupid blue bedroom is going to be the end of me.)
The Look: Blazer: Kenar via Marshall's (very similar at Target) Sweater: LOFT (similar 1, similar 2) Pants: Express (the Columnist, slim fit) Flats: Merona via Target (exact)
