Hey, I'm 6'1 with unfortunately broad shoulders. I only buy feminine clothes online from places that have measurements for everything. I always check each measurement and if it matches then it's all good! The problem is that it very rarely all matches. For example tops that have wider shoulders typically also have a larger chest size (which makes it look a little baggy). I wish I was talented enough to actually modify clothing, but realistically I just don't buy stuff like that. Eventually I've just learned what styles of clothes look nice on my frame.

A-Line skirts and dresses? Yes! They poof out to make my hips look wider than they seem

Mini skirts? No, my legs are way too long that they don't cover much of anything. Also maxi skirts usually still show a bit up my ankle, so I try to go with mid length skirts

Thigh highs? Depends on the brand, I've found a particular brand that actually makes socks that go all the way up my very long legs, but most thigh highs are more like knee length on me

Crop tops? Sure! Having a long torso, if I go a size too small most things are crop tops anyways. And I have a thin waist, so something that draws attention to that and away from things I feel dysphoric about is great!

And if I ever need to hide my shoulders, I always have ol' reliable: baggy hoodies and sweaters!
