I have been going to the Saturday T-Girl Nights at Hamburger Mary's in Long Beach for three years now. (Jamie, the gal who runs it, has also started having a second event on different Saturdays at the Hamburger Mary's in West Hollywood. It is not as established as the one in Long Beach and doesn't have as many attendees. She also runs the Tuesday night karaoke party at the Long Beach venue.) There is also a trans night at Club Cobra in North Hollywood every Thursday.
The clubs all have different vibes and while many of the same people attend each of these clubs there are some differences. The Saturday Long Beach event has been going on for many years and has a fairly large and devoted attendance group. It consists of individuals in transition, CD's and admirers (->-bleeped-<-s). They play EDM music with a Latin beat. The dress varies with some going club hot and others going for a more refined look. I've even gone in shorts and cute top. I've also gone with some pretty daring club wear.
The Tuesday Long Beach event is a karaoke night and the people tend to not get dressed up.
The Saturday West Hollywood event is new and is still trying to get it's vibe together but I suspect that it will be very much like the Long Beach Saturday events.
The trans night at Club Cobra is a much different vibe. It attracts a lot of ->-bleeped-<-s and has a fairly large contingent of working girls looking for dates. The outfits are mostly club wear.
There is at least one other event that is just starting up in Long Beach and I'm not sure what the schedule is there. I've never gone and so I can't really tell you much about it.
I've become a member of a private club in Hollywood that requires all black clothing and I've really gotten into that scene. I've posted some of my outfits that I wear there on the you look fabulous thread. I've gotten way more bold there than I ever did at any of these trans clubs.
