I realize there's a huge difference between a 13-year old's likes and those of an 18-year old, so rather than grasp at straws I based this gift guide on the preferences of someone right in between: my 15-year old cousin B.

Vera Wang Princess Sparkling Creme Perfume ($38) I would have been all over this 10 years ago. Alas, am unquestionably an adult now. Boo. :(

MAC Little Darlings 5 Pink Lipglass & Lustreglass ($29.50) Who wouldn't love 5 mini lippies from MAC? This set has Fleur Delight, Song and Dance, and Magnetique Lipglass, and Flashmode and Little Vi Lustreglass. If the girl on your list isn't the pink type, there are also sets in Coral and Neutral.

Sephora Ultimate Blockbuster ($48) For a young girl just starting out her collection, it's a dream come true. 71 eyeshadow shades, 13 cream eyeshadow shades, 5 blushes, 1 compact powder, 60 lip glosses, one lip liner, one eyeliner, 4 brushes, and 3 sponge-tipped applicators. Whew.

Lancome Juicy Tubes Holiday Set ($39.50) Eight mini JTs in some pretty impressive shades, including several limited editions: Juicy Tubes Smoothie in Spring Fling, Juicy Tubes Jelly in Grand Cafe Creme Brulee (limited edition), Juicy Tubes Smoothie in Simmer, Juicy Tubes Smoothie in Fifth Avenue Frosting, Juicy Tubes Smoothie in Ginger Palace (limited edition), Juicy Tubes Smoothie in Maharani Jewels (limited edition), Juicy Tubes Smoothie in Pink Horizon, and Juicy Tubes Smoothie in Sun Bro.

L'Occitane Hand Indulgences Hand Cream Trio ($25) One each of Lavender, Cherry Blossom, and original Shea Butter, housed in a pretty little box. My cousin B loves these, and I'm sure she can't be the only one!

Aquolina Pink Sugar Luxury Gift Set ($95) I'm not the biggest fan of Pink Sugar, but it's a huge seller and this set would make a Pink Sugar enthusiast very, very happy. Includes 8.45 oz Perfumed Massage Oil, a 1.7 oz Eau de Toilette Spray, a 3.38 oz Hair Perfume, a 8.45 oz Body Mousse, and a 6.76 oz Glossy Body Scrub. (Wait. Why does body scrub have to be glossy?)

Harajuku Lovers Solid Coffret ($60) These are just so cute, I want them for myself. Solid perfume versions of all five Harajuku Lovers fragrances: Love, Angel, Music, Baby, and G.

Philosophy The Cookie Exchange ($30) Four delicious 3-in-1's from Philosophy: Chocolate Chip Cookie, Oatmeal Raisin, Snickerdoodle, and Sugar Cookie. Almost as good as the real thing!

Bare Escentuals Tutorials - The Rocker Eye ($38) 95% of teenagers at the mall seem to be sporting the black-rimmed eye! This kit from Bare Escentuals takes it up a notch and helps create a really gorgeous smokey rocker eye. Much, much better than a thick circle of Blacktrack, and more fun, too.
