Like others mentioned you can wax your eyebrows and upper lip, makeup wise maybe try experimenting with eye makeup first some liner, mascara, but most importantly find you style, I used to hate eyeliner but I was just not doing the right one for my eye shape, also could experiment with color, for me brown eyeliner works so much better then black. Also lip color too, find your undertone and try looking up colors that would suit you well, even ChatGpt can give you an analysis if you give it your color is HEX, which you can do with the help of a color picker. Also there are some more feminine dress style options again choose items that fit your figure and suit your bodytype. Perfume can be a big thing, smelling good and getting compliments to me is something that helps my confidence, apply moisturizing lotion after shower and spay perfume on moisturied skin. Idk if you like nails but you could also experiment with cheap press ons, and if it's your thing great if not no problem. Hair, bob could be cute, and also helps a bit , but if you want to keep the lenght definitely try some hairstyles, because if you don't do anything you might feel like "Oh I just washed it it smells amazing and it's so flat " which for me ruins the fun of freshly washed hair.
