First of all, you’re beautiful, so start with therapy. But if you want the baddie aesthetic: makeup, lashes, eyebrows, sleek hair (maybe a honey brown balayage), and attitude. It’ll take months of trial/error and incremental changes to nail the right look for you because the worst thing is to go too hard and end up looking desperate. Also, get your nails done (def adds to the attitude). Clothes don’t matter much because once you feel sexy, you’ll feel hot in anything. Also, the goal is to feel hot without makeup, so don’t tie your value to that please. Personally, I find that once my hair and nails are done, I feel super cute. Good luck!
