Cheer up, Cora Emmanuel. You look hot and not in a sweaty, summery way. If your hair's not cooperating even after you've stuck it in a bun, just emphasize the frizz halo even more by running your palm over the front section. (Though you'll want to wear a polished outfit for contrast. Perhaps something 3.1 Phillip Lim?)
In a perfect world, all brushed-out curls would end up looking like Bottega Veneta. But even if *your* frizz more closely resembles Mia Thermopolis's, you can do this: Just make a deep side part, applying product to that section only, pin, and fluff.
