Undine's just arriving at the pool in a tankini as the skittish cat of a young man pokes around. She's a short teenage girl, with blue hair and blue eyes, a blue mark in the shape of a down-pointing triangle on her chest above the neckline of the halter-top of the suit.

"You'll be more comfortable swimming in less clothing than that. Both Tommy Bahama and Bric-a-Brac sell swimsuits."

And with that comment, she moves to the deep end and jumps in, though she swims nearer to Dmitri to continue the conversation once she's gotten cooled off (not having realized the effect getting wet might have, yet...).
