All I can say is that my sister is going to be running the Pittsburgh Spirit...the Penguins version of the Ice Girls, and she asked if I could find out what fans like/dislike about the Ice Girls.
since u put it that way, make them accessible especially to the little kids, b/c they look up to them a lot. Try to keep the outfits classy. They really don't do much, have a few available during the period on the concourse.
Most fans love them or hate them. It seems that they do alot of the rpublic relations type of work being at the Isles draft party and doing work with team mascot Sparky the Dragon and other off ice things.
Check out the Isles web site for some info as to what they do as well.
They have to be in areas where the fans can get up close to them. They will be able to move product because the guys will shell out money to buy anything if it means getting a good look at one of them. I know, when in a box last year one came in selling hats and my son and I were gaga (she was beautiful, sexy and about 20). dont you know we both got new hats even though we already have a few.
Tell your sister its about one thing only, dont be fooled. Its about being sexy, period. Thats the appeal.
