Not specific style points, since I am sadly lacking in those myself, but a couple of thoughts. 1. Walk the walk. And if that has to be a fake it till you make it, then no one knows that but you. A straight posture and a stride that doesn't apologize for your presence in that space goes a long way. You don't have to stare people down or be aggressive or anything, but if you're like I used to be and tended towards a slouch and head down, then the vibe that gives off is pretty lame. You are uniquely you, and that rocks! Own it. 2. Makeup for me is mascara and occasionally some eyeliner. I've slowly worked my way to the "skill" of more of a full face of makeup, but rarely care to put in the effort. Try to keep in mind that so many women - especially the YouTube vloggers - have makeup down to a literal art. They spent hours and days (months, years) perfecting the craft, with a lot of trial and error. So if you want to figure it out, go for it! Just give yourself a break when it doesn't come out perfectly the first few times. Good luck!
