My youngest daughter has two teen-aged sisters whom she wants to be just like. When she turned 11 I re-invented some shower and party games to appeal to that "I want to be a teenager" attitude.  As each girl arrived I pinned 3 or 4  big plastic brightly colored clothes pins on their blouses. The girls were instructed not to use the words "birthday" and "Misha" (my daughter's name).  If they heard another girl say either word they got one of her pins.  The girl with the most pins in the end wins. (Of course we counted pins prior to singing "Happy Birthday!") First we played "Kiss the Teen Idol" I found a poster of one of the "hottest" teen idols and the girls each got to apply bright red lipstick. We then blindfolded the girls, spun them around, and let them kiss the poster--(We placed the poster on the sliding glass door so that all the missed kisses could be easily cleaned.) The girl who got closest to the lips won the prize. Next we played "Musical Nail Polish". I gathered some of the nail polish we had around the house, especially older sisters' cool funky colors. I put one less bottle than we had guests in the center of the table (e.g., 10 girls = 9 bottles of polish).  While we played her favorite music the girls circled the table. When the music stopped they grabbed for a nail polish and began polishing. The girl without a bottle was out--just like musical chairs.  When the music started again we removed one more bottle and started again. Last girl in wins the prize. (NOTE: This game we played out doors on the patio table, which by the way was well covered with a disposable paper table cloth!) We also played "Who knows Misha Best" I asked various multiple choice questions such as "What day was Misha born?" "Misha's favorite color is..." Misha's favorite song is..." etc. The girl with the most correct answers won. Finally we played "Misha's Going Shopping and Taking With Her..." (This was a spin off of a shower game I'd seen where the mommy-to-be had carried around a tray with all sorts of baby items, the players were instructed to pay close attention, then were asked to list what the mommy was wearing including accessories.) In our version I filled one of my formal evening bags with pretend money, cologne, a comb, lipstick, plastic credit cards, a mirror, etc.  I told the girls to pay close attention and try to remember as many items as possible.  Then, as I told a story about Misha going to the mall (her favorite place) and why she needed the items in the purse: money to buy lots of cool stuff, credit cards--to buy even more cool stuff, a mirror to make sure she looks great, etc., Misha pulled each item out of the purse and did her best Vanna White impression making a big display of showing each item. Then Misha stepped from the room and I asked the girls to write down the color of Misha's nail polish. We finished out the party with cake and ice cream, the girls danced around to pop music and got to take home goody bags filled with stickers, lip gloss, necklaces purchased at the $1 store and of course candy. (Most of the game prizes were also purchased at the $1 store so the whole party was relatively inexpensive--a lot less than bowling, movies, or pizza party) During the course of the party we had hot dogs, chips and dips and pop. The girls had a great time and the whole theme seemed to fit perfectly with the in-between age of the girls....not little girls anymore but not quite teenagers.
