(Almost) Complete Transformation

You grabbed a black T-shirt of his, blue shorts and white socks you put them on feeling your body shrink and your perspective lower a few centimeters, excited to see yourself controlling Jim's body you went to a mirror and saw... Your face, disappointed, you exhale.

Shouldn't you have his body if you have his clothes? You have his dick and his height, getting his shirt off you see that you do have his body since you can see the birthmark he has on his upper back.

Then, you deduce, you need an accessory he uses on his face, most likely glasses like yours to fully have his body.
