Is there a hint of a future job according to this character (spoilers)?

Dancer was hinted at when Lyse during SB's MSQ mentioned briefly that her sister, the real Yda was a dancer and the dress Lyse wears originally belonged to her.

I don't recall them ever claiming Yda was a dancer, only that the dress belonged to her. The Lyse minion text even pokes fun at the fact that people thought it looked like a dancer outfit!
