I like the way you think. And it would fit in a stocking so nicely. I suggest the “candy” giftwrapping style, with dangly ribbons on the side which will vibrate cheerily should she shake it just right before unwrapping it.
Got to fit in a stocking and leave room for more stuff, though.
I don’t wanna know who is buying a dildo big enough to fill a stocking alone!
Hohoho.
If she does her own eyebrows- fancy tweezers- Tweezerman are good.
If you live somewhere cold- hot water bottle and cover or microwaveable wheat bag.
Small coin purses, or a tiny handbag for smart occasions
A USB stick/flash drive- everyone needs one of those
A handbag sized (e.g.50ml/2oz) tube of expensive hand cream- something like Elizabeth Arden 8 Hour Hand Cream if she is into that.
Mobile phone cover
Fancy Keyring
Nice addressbook/organiser/diary/notebook
Insulated travel mug or water bottle- for her favourite beverage at ideal temperatures!
Lipbalms- no-one can have too many lipbalms. I like Carmex, EA8HC (again), Lush and Vaseline- the one with cocoa butter. YMMV.
A mix CD- corny, but who doesn’t love them really ?!
I think the key for stocking fillers is to get everyday things, but nicer versions than they would buy for themselves.
Stocking stuffers for women?
The best things to put in stockings is women!
I ended up getting her 6 pairs of her favorite panties, 4 pairs of goofy warm socks, a nighty from Victorias secret, and some cute long john type pj’s.
Ohh and although she doesn’t lack toys I got her this http://www.amazon.com/Trojan-Pleasure-Vibrating-Personal-Massager/dp/B003WLUYJQ/ref=pd_sbs_hpc_1
I just need to get some tangerines and a few little chocolate doo-dads and I am done.
She will be smiling come Christmas morning…
Thanks for all the great ideas everyone.
Merry Christmas
Hope all y’alls have a wonderful Christmas and get everything your heart desires.
Sounds like you may also be smiling, come a bit later Christmas day… 
May you both enjoy the presents greatly.
