She tries to pull them up

"Oh my God!" Tanya gasps, looking at her five students, and then glancing over her shoulder to make sure no one else was watching before bending down and tugging her leggings back up.

She managed to get herself partially covered, but as they reached her waist she spotted the tear. There was no way she could wear these anymore, without constantly holding them up at least, and that was really not an option for a yoga class.
