It's a really good idea. I hope everything will be OK and he will appreciate it. We can order t-shirts in order to support trans men. You can choose the print, size, color, and fabric that you like and just order a t-shirt. Recently I've found a great site
https://matohash.com/pages/same-day-t-sh...ng-detroit with a lot of options for shirts and we can choose something there. Yesterday I've ordered a shirt from that site and was really impressed by the quality of the shirt and when I called on the phone number the staff was so polite and kind to me. The shirt came on the same day I ordered it. And everything is OK like fabric and it's not cheap.
