I'll take any "t-shirt" and cut a small hole in the back of the sewn collar, right above where the tag is. I feed each mic into the hole & run them on either side of my neck & use a small paperclip to hold the mic in place. It's nice because when you run in a hat, you sometimes get phasing from trying to look down & check levels, and, you can move your head around. Only downside is you're losing about 10" of height on your mics or if you are adament about X-Y,ORTF, etc...
