Here is a round up of gifts I think she would like. I pulled her name this year, so it's possible some of this may be under the tree ;)
My sister likes unique jewelry - something she won't see anyone else wearing - and this seems to fit her personality. Not too girly, but edgy in a cute way. Plus she is a farm girl, so there's that :)
I think it would be a nice addition to her room to have a large statement piece. And if it's horse themed, so much the better!
3. Nail polish
Because you can never have too many fun shades! Plus since nail polish is relatively inexpensive it's a nice stocking stuffer.
4. A fun game
My sister likes having her friends come over to spend the night, so a unique game (that doesn't take too long to play) would be something I could see her enjoying frequently.
5. Cute clothes
What teen doesn't like getting clothes for Christmas? A hoodie, jeans, name brand t-shirt or accessory will always be a hit!
