There are dress shirts with snaps - my dad loved them for some reason and had a bunch. Are snaps any easier?

Also, does it have to be a dress shirt or could a boy's long/short sleeve polo work? Those are easy to get over the head pre-buttoned (leave top button open).

Some brands have adaptive clothing.

Amazon has a bunch of potential options. Maybe also pre-button the shirts in a size larger than his size, so he can get into it over his head.

Would this work?

My DS has to dress up for an event at school and will be taking the outfit to get ready there. He really struggles with buttons despite all the OT he received. Are there any brands that I could get? Also, is there a local store he could go and try on? Thank you
