From my friend Jenn comes this link to Chosen Couture. The "oy vey" baby-doll tee is cute, ditto the one that says "חי maintenance" (חי = chai, which means "life") and I would actually consider a workout tank-top printed with "shvitz"...

...but I laughed the hardest at the Doggy Yarmulke and Tallis set. "He responds to commands in Hebrew, so why shouldn't man's best friend have his very own yarmulke and tallis? Kasher your pooch with this Star of David printed set - it's perfect for weddings and Bark-Mitzvahs!" Oy vey, indeed.
