Vestiflux is a xenogender/mutogender that fluctuates based off of what one wears or how one presents.
The intensity of the gender does not have to line up with the presentation. For example, one may feel 100% androgyne when presenting femininely yet feel completely agender when presenting neutrally.

Flag
The flag was created by the same person on the same day. The meaning is as follows:
"The white and black are derived from the genderfluid flag. The pink and blue are picked from the genderflux flag, and both have the same meanings: no gender, all gender, femininity, and masculinity respectively. The yellow is picked from mutogender but can also mean nonbinary."
