Clothing options for summer (concealed carry)

Hey all, I'm fairly new to concealed carry.. maybe going on a year total. I've found that I really like tucking shirts into my holsters for added concealability. Using a thin undershirt and than a regular tshirt on top. The problem with summer time, is... i'm getting too dang hot lol.

I'm wondering what you guys do? Just run a longer tshirt, or maybe there are undershirts designed to keep you cool in the summer?

(ah crap, just noticed this is an 'open carry' forum LOL. my bad.)
