You'll notice that "Spotty's" boobs are much smaller in her uniform. The real reason was i was able to make her outfit fit better with 'standard' breasts, but a 'in character' reason would be like the following:
"Not much is known about this race, including its name; although it is believed that they are related to the Delvians due to their appearance and self-admitted plant-based biology.
"From sources that have chosen to remain nameless, it is known that, when sexually aroused, their body goes through subtle changes to be attractive to her mate. In at least one case her pseudo-mammary glands have increased in size, as well as her Gluteus Maximus. It is also believed that this race emits a 'pollen' thats acts as an aphrodisiac.
"According to unconfirmed reports, applying gender to the race may be a misnomer, as some have reported seeing an alleged female of the species with obvious male genitalia
"Finally, it is known that when facing possible danger, the race assumes a more fearsome form, with thorn-like protrusions from the fingers and the 'scalp' ".
Okay, way too much information, but I'm a gamer, so I'm good at coming up with backgrounds for RPG characters ^_^
One final comment: For some reason the walls buldged out when I did the 'clothed' render. I tried to save the file to try again, but my memory crapped out and ruined it (at least I got that one off).
