I do sometimes wear diapers to work.
Sometimes I find the diapers distracting but sometimes I get more work done when wearing a diaper.
After awhile you can get used to wearing diapers and then focus on your work but at first wearing diapers to work for fun can be a bit distracting.
Still wearing diapers to work is good if you work in a call center, office etc so you can just pee the diaper and continue with your work.
