Honest take, there's nothing lewd about Tsareena's design. She's at least modest compared to other waifumons, take for example how Lopunny has actual curves and is naked or Gardevoir's dress being open enough that she exposes her legs like a slut if the wind isn't kind or Salazzle having a subtle womb tattoo.
Meanwhile what does Tsareena have, a fat silly skirt? Even the boots don't look like the'd fit with the dominatrix attire.
