16 year old girl in our house. Her stocking will include:

New leggings for the gym
Earbuds
A card game
Lip balms (can never have too many)
Gift cards in small amounts ($5 Starbucks $10 ice cream store)
Initial necklace
Earrings
Warm headband & matching gloves
A couple of pieces of makeup
Skin care products

What about a Shutterfly mug with some pics on it? Always good with some hot cocoa. Also a Contigo for hot and cold drinks at school.

OP here. Thanks to everyone who took the time to respond. This was helpful and I appreciate it.

My 15 yr old DD would like the following for stocking stuffers:
fuzzy socks
pom pom winter hats
those cord protector things that are shaped like animals and help make sure you don't wreck your phone charging cable
water bottles with stickers to put on them
new ear buds
scrunchies (yes, for hair, they've come back)
spotify subscription (we use a gift card box to represent this)
starbucks gift cards

My 15 yr old DD would like the following for gifts:
apple airpods
new set of pencils for sketching
new sketchbook
a banjo
a film camera
new clothes

I'm sorry about your mom.

Earbuds
Rolled up hoodie
Fun pens

Ponytail holders
EOS lip balms
Sneaker balls (those balls you put in sneakers to make them smell better)
Cute sticky notes
Wet brush hairbrush--they make a mini one taht would be good for a gym bag or locker

Cool water or hot liquid bottle? My DD likes to drink tea & was thinking of getting her something, so she could take it with her in the morning.

Cool socks. Everyone loves cool socks! Maybe something reflecting something she likes? Mine likes art socks (major works of art on socks -- my favorite is Munch's "The Scream" -- hahaha).

Cherry chapsticks or cooler lip balm (mine prefers cherry chapstick).

Magnets for locker

Nice pen/pencil

Funky hat (like fur trapper hat or Russian military hat), though I guess that wouldn't fit in stocking

North face gloves (Marshalls had them)

Cute USB drive (mine has one in shape of instrument she plays)

Erasers. (Mine likes theatre & has one that says "out out, damn spot")

My daughter is 12, but she's super into Lululemon headbands at the moment. I don't know how much they are, but a friend gave her one for her birthday and i she was thrilled. I had no idea they were a thing. Lip balms are also useful, and of course whatever treats she likes. Also thing for the phone if she has one, like a pop socket or long charging cord, might be good.

I would order a bunch of clothes online, have her try them on before Xmas, then choose from what looks good on her and put that under the tree. Chocolate and money and an ornament with her photo on it in the stocking.

My DD is also sporty, so here's a list: ponytail holders, headband for sports, socks, $15 gift card to her fave food place (South Block), cute t-shirt rolled up

DD is in 8th-grade, sporty, doesn’t wear makeup yet and isn’t really into bath products. She does use a particular body cream, so that’s covered.

I’d appreciate gift ideas, especially stocking-stuffer items that your DD likes. My mom is ill and I just don’t have it in me to be creative right now. TIA.
