What to put in bathroom basket?

I am thinking-

hairspray
deodorant
mouthwash
static guard
clear nailpolish

What else?

Besides what you wrote we are putting in:

Stain wipes (Shout wipes)
We put breath mints
Q-tips
Lotion
Asprin
Nail glue
Bandaids
Maybe Tums

Some cheap pantyhose/knee highs (the 2 for $1.00 kind - just for emergencies) would be nice to add.

Starlight mints peppermints (they look nice and are individually wrapped)

Hand lotion
Baby wipes (for makeup smudges especially)
Small pack of Q-tips
Safety pins
Nail glue and definitely the clear nailpolish
Hairspray can double as static guard
Band-aids, aspirin/ibuprofin
TAMPONS!!!

Bobby pins and some cheap ponytail elastics
Gum
Matchbooks (unless you're giving them out anyway)
Small hairbrush, pick, or comb maybe? (the travel kind)

There have been several posts on this in the last 2 months. You can do a search, really some great ideas on here!
