My girlfriend spent over $100 in one weekend playing some dumb freemium fashion game. She knows it's dumb and she's being ripped off, but she just doesn't think about it when she's just spending $1 here and $2 there.
Also, if anyone knows of a completely free game as close as possible to Covet Fashion - Shopping Game, I'll love you forever and invite you to our wedding.
espero a que nos castren o voy altiro a saquear un mall??

I don't know of any specific apps for sissy kink, but Covet Fashion is a good one for helping develop your sense of style.
