Just to nip it in the bud so it doesn't start a huge debate, the Korean and Chinese glams were made by the distributing companies (because that way the games abide by Korea and China's unique censorship/payment laws), not SE, so SE doesn't have 100% control to just port it into the US version like they technically do with the maid and butler outfits. So to get those it'll take a ton of extra support and way longer of a time frame.

(They are gorgeous though, just not easy for us to get.)
