I don’t really know about fashion, but I do find it helpful to learn about your body shape and focus on the form and what is flattering or not on your body. For example, a lot of trans women have inverted triangle or “strawberry” shape because of their broad shoulders. Others have more of an “apple” or square shape if their waist is large enough (usually due to male pattern fat distribution).

Reshaping the body by losing and re-gaining weight is a good long-term project, but in the short term it’s good to know how clothes are going to look on you.
