For trendy filipinos: hot brands?

Hi! Going to the phils in a few weeks, stayin in manila for a couple of days and gonna visit robinsons and sm and ayala malls landmark and whatnot. Havent been to the phils in a long tim and gotta know what the hot brands are when it comes to tshirt(prefarably slim fit v-necks) and slim jeans (levis?). Lalaki ako. Also i wanna get both my ears pierced for diamond studs, how long will the healing process take and whats the price for nice square diamonds in bacolod, or in general outside manila?. Salamat!
