I pretty much use one bag every day & am not a fan of switching out purses. I carry too much
But ... every now & then, I do change my purse to go with an outfit. Particularly if I'm going out for the evening. I will use this little leather baguette-style bag which is precisely big enough to hold my wallet, iPhone, & a little makeup. A friend gave me this purse in a clothing swap, & I love all the buckles.
For specifically gothy occasions, I might break out this big vinyl bat purse. It's not very practical in size, but it does look cool. This was a gift from a very sweet coworker.
Then there's this funky, punky little bag that's an army surplus bag I decorated. I don't use it much because I'm not a big fan of crossbody styles. But every now & then I'll drag it out since it's a good all-weather casual purse.
The pins are, from left to right, a "sleep" tab from Doctor Who, the Greater Bay Area Costumer's Guild membership pin, a toreador rose from Vampire: the Masquerade, "Runs With Scissors" (a joke because I sew), & the Pacific Division Championship banner for the San Jose Sharks hockey team, all surrounding a peace symbol patch, because I'm a damn hippie :-)
