Hole in cycling (triathlon) kit - Repair options?

Had a duathlon today, forgot my race belt, and had to pin the number.

Brand new triathlon suit and there is a 2mm hole in the front from one of the pins.

I’ll be taking to a dry cleaners tomorrow (they’ve done some minor sewing on non cycling kit before), but does anyone have any suggestions?

I sew up holes in my cycling kit myself. I see it as a badge of honour to be wearing kit scarred by my many falls in crit racing - the more ham-fisted the sewing the better.

Much like Rambo stitching up his own war wounds in the movies…
