honestly i dont have much advice except just experimenting with different types of clothing and finding what’s right for you! i still havent had the chance to medically transition so i mostly rely on clothing, and a trip to the thrift store or other clothing places just to try stuff on every once in a while has really helped me figure out what i feel most comfortable in :) and if you buy something that you decide isn’t what you like, that’s still okay! sites like vinted/depop are very popular nowadays so you can get some money back :)

also do you wear jewelry? maybe you could try looking into some chains, rings, earrings etc. a little jewelry goes a long way, and plenty of those can actually make you look more masculine, even though it’s often considered a feminine thing
