She's not going to feel uncomfortable at her natural body temperature, because it sets the baseline upon which feeling warm or cold depends upon. What matters is the relationship between body temperature and environmental temperature.
As an example using freedom units, humans have a body temperature of around 100 degrees, and tend to be comfortable at around 70 degrees, giving us a 30 degree difference between internal temperature and a comfortable environmental temperature.
Let's assume for easy numbers that twi'leks run 10 degrees warmer than humans, for a body temperature of 110. If we further assume that twi'leks have the same relationship as humans between body temperature and a comfortable environmental temperature, this places their comfort zone at 80 degrees.
If we figure that controlled environments follow human standards for sci-fi/fantasy reasons, this means that our standard 70 degrees will probably be a little on the cool side for twi'leks. It wouldn't be unbearable by any means, but it wouldn't exactly encourage the skimpy clothing that Aayla wears.
Obviously the above makes use of a tons of conjecture and guesswork, with my temperature examples involving personal intuition regarding comfort more than any real, scholarly knowledge about the subject, and depends entirely on twi'lek biology working similarly to that of humans.>>104711878
That's basically what I'm saying.
