I have the most recent handbook and WaveRider is correct, it says "we ask that you wear a red top (any shade of red is fine, but not orange, pink or purple) and solid color pants (preferably khaki)." I've worn various colored shirts (even striped) with a red vest and my STL has never said anything (other than he liked my vest). As long as the "red" is on top and solid, I don't think they'll say much. The only time I've heard of our STL saying anything to anyone was once when a new TM wore a somewhat see-through shirt with a black bra underneath...he made her put a hoodie on over it because it was a bit....shall we say....revealing:girl_impossible:
