A Twin Cities nonprofit that faces an uncertain future is now being affected by this weekend’s expected snowstorm.

Operation Glass Slipper, an all-volunteer nonprofit, holds an annual two-day event to provide teens in need with a prom dress, shoes, purse and jewelry. But this weekend’s “Princess Event” is being postponed due to the snowstorm and will be rescheduled for 8:30 a.m. to 4 p.m. March 16 and 9 a.m. to 4 p.m. March 17 at Southdale Center in Edina.

To get a dress, students must get a referral form: bit.ly/2CgltyT. To volunteer at the event, go to bit.ly/2UkmPPP.

The nonprofit that Pam Philipp, 68, of Inver Grove Heights launched 13 years ago now faces an uncertain future since she and nine other volunteers who help year-round are stepping down this year.

This year’s final “Princess Event” will, for the first time, expand to include ninth- and 10th-grade girls, likely boosting the number of teens they dress to a record 1,500 students. Dresses that aren’t given away for free this weekend will go to two sales afterward.
