If you've gone to the Volta sim at FFL 2012, Styles of Edo is a must-visit. Four of their Fashion for Life tuxes are down to 300L$. I got the Step Lapel one and wore it with SF's past dress shoes group gift, Edmund. Speaking of which, I also grabbed SF Design's rancher boots that were put up for 55L last Friday's sale. It's not there anymore, but check out how beautifully-made the pair is.
The skin I'm wearing is Heartsick's group gift Ritsu. Actually, I got this as a hunt item in FFL, so I had to pay a small fee. But if you've joined Heartsick's group, you can take it from the notices for free. I don't mind paying 50L though. Heartsick's skins are awesome and the small price would help cancer research anyway.
