When I first started wearing shirts like that, I would button down. After a while I realized it’s easier to start from the bottom and button up, because then you don’t miss a button and it’s always even.
…Maybe I had more of a problem skipping buttons than others
I will say with some baby onesies though I’ll button top down to the middle then bottom up to the middle if it has snaps that go round the legs because I always seem to mess up those snaps in the middle
Button down. Feel for the second button and hole and start there. I’ve gotten confused with dress shirts which have spare buttons at the bottom when getting dressed half-awake.
