Ladies,
I have to be brutally honest, as a genetic male our shoulders are definitely broader compared to the average cis women. It will be a different story if you started taking puberty blockers from age 13 and up then you will be blessed with a narrow shoulder to wider hip proportion.
If shoulders are problem or you wish to conceal their length, proper clothing will do the trick.
V necks
Scoop necks
Raglan Sleeves. If you dont know what a raglan sleeve is, review the link below:

Boat Necks
Turtle Neck
Round necks
Revealing your neck and chest will always give an illusion of a shorter shoulders.
Bottoms:
Flared Bottoms
Colored Pants (i.e. Blue, Red)
Bottoms with a lot of detail
Colorful shoes
The idea behind all these, is to focus the attention on the bottom half of your body and not on our upper body as it's quite common for trans women to have a heavier upper body set.
Avoid skinny jeans or tapered pants unless you are wearing a lose top to give an illusion of wider hips. Otherwise, you will look like a walking hanger.
Love,
April
