Also I'm colorblind. I've never felt more disabled than I have since starting transitioning π³
high waisted stuff is your friend, a lot of more fem stuff is meant to fit around the belly button or just below. If you're used to wearing dude clothes you're probably used to fitting stuff near your hip bones.
An easy thing to try to start building outfits is "big shirt small pants" or "big pants small shirt" to see what proportions of things look good on you. High waisted baggyish stuff will go a long way to making your proportions look like you have hips.
Take your measurements for shopping online using string then measuring it
Prepare for disappointment; womens clothing is a lot harder to size. Just because something doesn't flatter your body doesn't mean you're failing, it's hard for every fem person. A combination of HRT changing your figure / finding out what works for you will expand your wardrobe options. Pay attention to what works and persevere
It's a process.
Learn how to take care of your hair properly. Google around for hair types, figure out what yours is, then google further to find recommendations on washing / conditioning routines / products. You probably need to shampoo than you have been, and condition more than you have been.
Don't panic about browsing the women's section. No one's watching, no one cares, the staff aren't paid enough to give a fuck. It's relatively common for even cis straight men to shop partially out of the women's section. Lots of cishet men fashion influencers will recommend this especially since more cropped shirts are in style right now. If you're too anxious to use the changeroom, just buy a bunch of shit and return what you dislike, no one cares.
Good luck comrade
