Well, if you are way too old for halloween, it's a cool outfit for you and your gal pals!
First, grab a light pink jacket or another color you would like. If you don't have one, dip a leather jacket in pink paint or another color you and your gals like and let dry. On the back, use permanent marker to write Pink Ladies or your group's name in cool handwriting.
Wear tight-to-skin leather pants, leggings, or colored jeans. Wear high-heels or ballet flats or some girly but retro but trendy BUT edgy shoes.
Curl your hair and put in a frizz-free ponytail. So, now you have a stylish Pink Ladies attire. Now you need your Kenickie or whoever. Go out there and grab a bad boy 'tude-d boy and yeah!
Add members to your group, they should probably have your style and no goody-toe-shoes like Sandra Dee. Grab a bunch of ladies you think will complete the group. Now, if you like a girl but she's too clean-cut, all you must do is give her "Pink Lady" lessons. Hey, if you are too young, it's not the best idea to get drunk and full of smoky cigarettes.
