@jenn soft, thin, womens' size tshirts with an acceptable design (no words) and acceptable background color (not white).
zip-up hoodies in womens' sizes with the same design considerations (but bright colors are ok here).
nice backpacks are handy, right? or like a laptop bag?
anyway, i don't know how big/expensive you're considering, and i'm probably not even in your target audience, but there ya go!
(btw, if you want to go full chaos-mode, nothing beats a commemorative decorative plate)
