Um, I swear my shoulders got smaller. Then again, that could be due to muscle loss -- so there is hope! They will appear to go down some that way. I know my height hand feet size have change (smaller). My hips have grown out -- yes, I got growing pains and it hurt!
so, I don't know, maybe your age can affect a few small things with your structure -- but so can change in muscle mass.
I wouldn't expect to be 5'7" if you're 6'3" or something, just small changes. I'm 5"8' now and I used to be around 5"10'-11-ish (my licence still says 5'11" -- but I can't see myself ever being that tall!). I'm 5'8" last I measured, anyway, which is smaller. I don't know why. Muscle mass loss?
My feet size (in mens) was 10, but now (in mens) it's 8 -- yeah, I get a lot of skater shoes. I usually get 10 in womens, I can fit 9's, but I like 10's 'cause they are more comfy and I can slip them on and off. LOL I like the extra room. People think it's funny when I take off my shoes and my feel look way smaller. LOL Also, ATM, my shoes add an extra inch to my height, so I shrink every time I take my shoes off. LOL
