@Eve Skater dresses. Also, usually I find my shoulders look better the less I have on top of them. Tank tops are actually pretty good for shrinking your shoulders, despite what you'd think. Match them with something loose down below, be it a skirt or harem pants or whatever. Also, raglan tees (like your stereotypical baseball shirt) tend to minimize shoulders if they're dark there.

Also, hormones help a little. A lot of what we think is bone structure is really muscle that rearranges a bit on HRT.

@Eve switch with me?

but also -- play around with clothes! the raglan idea is a really good one. pair that with a button-up tied around your waist and you've got a look goin'. unfortunately, i don't know a lot of other tips and tricks. if you can go to a thrift store or something and mess around with styles, you'll probably discover clothing types that'll help you out.
