I really like Samantha Thavasa/Vega bags. They're quite popular over there in Japan and it seems like they're always expanding their brand and their styles. I know recently, (as a lot of people on this thread pointed out), they have a lot of celebrities design their bags, it's interesting to see how they never have Japanese celebrities design for them.
Like for example, they've had Paris Hilton, Victoria Beckham, Penelope Cruz, Tinsley Mortimer, etc. design for them, the celeb. designers have never been Japanese. I guess it just adds to the Japanese fascination with foreign American celebrities.
One of my favorite designs from ST was the ever-so-popular canvas bag with the wooden handles. It's from a while back, but whenever I would visit it was all over the popular magazines (JJ, MORE, etc.):

Even though I'm much more into European designers, I can see why Samantha Thavasa is such a hit to "consaba" (conservative) looked women and women with a wide range of styles.
