Her jeans snag

As Megan reached the top of the ladder and tried to pull her shirt free you can't resist the temptation to have lightning strike twice.

With a snap of your fingers, she slips for a moment, her jeans snagging on the ladder and locking firmly in place. The button comes off the jeans, and she falls backwards, suddenly finding herself hanging upside down on the ladder, her ankles still caught in her jeans tying her to the ladder.

She was trapped. Upside down, and above her ankles she now had nothing but her underwear. Not only that, but the fall had once more bounced a single breast out of her bra, her nipple poking up over the top of the fabric, hanging their, flailing.
