Has anyone figured out which store to buy Trevor's clothes in GTA V?

You get different clothing options at different stores. So I bought him a nice shirt and new sunglasses at SubUrban I think

I am tempted to take him into Ponsonbys (spelling?) just to see if they'll even sell anything to him

LOL Posonby's? Oh god.
