[Coding]alternate clothing

Hi,

I need some help about clothing script/coding, i need to know how to enable “alternate” clothing on ped, for example how to set “uppr_004_u_1” on Trevor.

i already know how to set “uppr_004_u”: PED::SET_PED_COMPONENT_VARIATION(PLAYER::PLAYER_PED_ID(), 3, 4, 1, 2);

But didnt find a way for “uppr_004_u_1”.

Thanks.
