About once every four/five months if I like the HA I have but feel a change in order. I'd like to change my HA more often like I used to but figuring out a nice outfit, especially one that matches is time consuming. A huge wardrobe takes awhile to file through.
It varies. Rarely daily. Normally once every couple of days or each week. If it is something I really like do occasionally leave it longer. Don't think anything has lasted a month unless I'm not around for whatever reason.
Every couple of days I guess ^^ What keeps me creative is Daily Item it used to be a cult but because of some construction work it is now a temporary forum topic and each day someone posts a cheap item and you can use that item and make a HA with it (: Afterwards you post it and can look at how other users worked with that particular item ^^ It's a lot of fun because you don't have to do it every day but whenever you feel like it or like the item of the day you can do it and I am always surprised how my avatar turns out in the end ^^

I usually only change mine once every couple months. I used to change my username along with it but that got a bit expensive.
usually a couple times a week. i save ha's that i've made in the past and tend to cycle through them, but only changing them slightly. :3
Well, it depends, but normally every one or two weeks.
It depends on how active I am on subeta. Sometimes daily, other times (like now) it can take months.
I change it seasonally lol. I've maybe changed it two/three times in the past year? I want to be more involved in doing it more frequently but I'm too lazy haha.
I would like to change mine more often but it never dawns on me, lol. I kept my Halloween one until almost Christmas last year.
i don't change mine v frequently, maybe only once every few months... i need a lot of time to make a new HA so i need to make sure that i have sufficient time to make a new outfit lol i also like to focus on whatever new item i'm currently infatuated with, but since i don't have a lot of sP, i don't get new items that i adore very often (rip me).

I'm change pretty often, but it varies with my schedule. If i'm in school, it's less. Holidays or during events, it's daily, or there abouts.
usually change mine 4-5 times over a short period of time, then take a break for like months lmao
i usually only ever change mine for events/holidays but my semester just started so i indulged in a lil retail therapy and now i can't stop playing around with layers (shrug emoji) i've changed my outfit three times in the past three days i'm unstoppable
I change every few days, pretty much just when I get sick of looking at my old HA, haha. If I'm having a good day and my HAs turn out nice, I like to just mess around in the wardrobe and make a bunch of them. I have 10+ saved HAs right now, so when I feel like changing I just put on one of those outfits :P
i change it when i have the time/nothing else to do on the site or if i get a new item i really want to use :)
Way too often. Sometimes I'll keep an HA around if I'm really liking what I've done... other then that, daily.
