Most regular-sized American condoms seem to be about 2" wide when laid flat (i.e., 4" circumference). See this chart:
Shop Butt Plugs (Huge Selection)
So the typical condom is probably ideal for a 4.3-4.8" girth.
What type of Kimono were you measuring? According to the chart above, some Kimonos are only 1.7" across, or 3.4" circumference. That should definitely fit snugly on a 4" girth.

I was 4.2 EG at that time. It seemed the beyond 7 condoms worked better and didn’t slip at that size.
Condoms very often slip off of me even at over 6" of girth. If you produce a lot of pre-cum, it’s very hard to keep a condom on, no matter its size.
