Actually, correct me if I'm wrong, but I believe Nu/Lambda you can see the navel as well, as I'm guessing it's suppose to be skin-tight. But yeah, pretty sure it isn't skin-colored for Mu.
Nu/Lambda were tempered in a controlled lab environment when they were placed into the cauldron. Mu was tempered in a completely different way. Its quite probable that the spiffy jump suits Nu/Lambda where were placed on them before they attempted tempering and that they were designed to survive the process. Mu was tempered in a process that was completely different and she was wearing a regular NOL uniform when it happened, elements of the NOL uniform are still present in her current clothing so we can most likely assume that it got heavily damaged by the tempering process.
