The slit ripped

The slit of Lauren's skirt had ripped, spreading upwards. It originally had gone from her knees to mid thigh. Now it came all the way up to her hem line! Her entire white thigh was visible, plus the edge of her panties. Even worse the skirt no longer held shape, now flopping wildly, risking showing everything from her waist down!

Lauren blushed brightly. She quickly rose, using a hand to smooth her skirt back into place, pinching it on the side to hold it together. She looked back. Nathan had not seemed to notice her skirt, looking at the score keeper instead. Then Lauren saw a nearby old man, belly laughing and looking right at her. Knowing how much leg, and maybe some pantie he'd seen, Lauren flushed brighter. Taking careful, small steps she went back over by Nathan.

"Is something wrong?" Nathan asked, looking up at her flushed face.

"NOTHING!" Lauren blurted, not wanting to reveal her skirt rip.

"Well, you have another shot." He said.

Lauren considered her options. She could potentially explain she wanted to leave, but that may require explaining her skirt. Short of that she could just play on, being careful to avoid any unwanted exposures, so Nathan would have no idea. What to do?
