I've changed mine twice today; though the first change was for a look I made in the past, my current one is a new look. Though the amount of times I change depends of there is an event going on, or sometimes I'll try to season match my look but I'm far less successful with those attempts. I tend to wobble between frequent changes to holding a steady look for a month or even a few months.

I probably change mine whenever I feel bored with what I got on, or I find something cool to try on.

I do it everyday bcause there are so many items I want to wear x_x

I change daily or ever less than that. I like to try something new

I change mine whenever i can come up with a good theme, have time to look for nice items, find some key items i really like and get enough monies (hardest part as a newb. ugh), and sometimes i change it daily until i can come up with a combo i like. Overall changing the HA is a big part of why i really liked Subeta's system, it allows for so much creativity and lets me relive my mabimbo days, so i'm trying to put effort into this.
