Welcome! Wear an untucked tshirt and or move your buckle off center away from the body of your guitar (above your front pants pocket on under the headstock side of your guitar.) If people ask you why your buckle is off center, just tell them you play guitar and they'll understand. I always have a tactical knife clipped onto the front pocket of my pants (on the guitar body side) which I always have to remember to take off and lay on top of the amp while I play.
