Not really considering that Tip-Top Shape also shows Sissi in her underwear for many seconds. If one counts everything, the last time we see Sissi in her underwear (a little) is in Xana Awakens, the prequel and special of two episodes basically. Xana awakens aired after the second season, so, this is basically the last instance of Sissi in her undies...I don't think it's a coincidence that a lot of her body is covered with that red dress she isn't wearing (yet), it really feels more sanitized compared to previous scenes of Sissi in her underwear.
