go for it! and hey if you have the means you could always make one :3
happy thrifting! dont be afraid to try something out of your comfort zone, can always pass it down/donate/sell it later on. I've found that a LOT of the clothes I got early on fit amazing now that I'm on hormones and have put on some weight that I needed.
baby trans phase is absolutely real, but after that i managed to pass well enough pre hrt by just tailoring my clothes to my body type and putting some makeup on. it only gets better from there
