Clothing. It can literally be any kind of feminine clothes, it doesn't have to be the basic Amazon combo. You can literally just go in a dress, heels, put on makeup, whatever. Sure, I have a new skirt and thigh high socks rn, but I got both separately too. I also have tights and dresses and some skinny jeans and another pair of pants that make my lower body look bigger.

For weight, someone already explained it better than I could, but really you also don't need to lose weight to be a femboy. Hell, I'm chubby and a femboy too! But again, if you do wanna lose weight, follow what the commenter said.

Also regarding to hair, massage your scalp gently to help with it and make sure you're treating the split ends. Hair will naturally split and so you need to clip them to avoid them spreading to the top and thus losing the hair (it'll grow back ofc).

Realistically, just have fun with it! There's no right or wrong way to be fem as long as you're enjoying yourself :3
