cammi top

遭難したTrishaは実際はずっと一人で山道をさまよっているのですが、ボストン・レッドソックスの投手、Tom Gordonの大ファンなので、少女の頭にはよくTomが出て来ます。
Tom wanted to know all about her, it seemed--her favorite classes at school, why she thought Mr. Hall was mean for giving homework on Fridays, all the ways Debra Gilhoody had of being such a bitch, how she and Pepsi had planned to go trick-or-treating as Spice Girls last Halloween and Mom had said Pepsi's Mom could do whatever she wanted, but no nine-year-old girl of hers was going out trick-or-treating in a short skirt, high heels, and a cammi top.
"cammi top" は９歳の少女がハロウィーンで着るのにはふさわしくない服のようですが、どんな服でしょうか？
・Dictionary.com: cammies, a camouflage uniform; a camouflage garment or garments.: The women had ironed their cammies and made sure their hair was perfect.
・The American HeritageR Dictionary: Garments made from camouflage fabric. Shortening and alteration of CAMOUFLAGE.
普通は複数形の "cammies" として使うようで、いわゆる迷彩服でしょう。
