I change when I feel like it, usually when I've been wearing the same outfit for a while and have gotten tired of it ^_^ I probably go 1-2 weeks in the same outfit before I change.
I have been wearing a "winter outfit" of sorts and not sure yet if i want a summer outfit or not D: but the sweater dress would probably leave my mayor roasting
I actually used to change it a lot too lol. But now that I've been playing for a while I only really change it if I find a qr code that I like, or if I find/come up with an outfit idea that looks neat... so maybe once every couple of months. I'm a bit too lazy to be bothered to change every day otherwise. xD
I change my outfit everytime I see something new that I like in ables! So it can be every day for a couple of days and then it could I don't see anything I fancy for a whole week lol.
I like to change outfits when I'm doing things like landscaping, or going to birthday parties, or sometimes when visiting another town. Also when the season changes!
I only change for special occasions. Like right now I'm wearing a leprechaun hat until St Patricks Day. Once that's over I'll go back to my usual choice of hat.
i change my outfit when i change my town theme. if i want a pastel theme town, my characters outfit is pastel. if i have an autumn theme town, warm colours it is
As of right now- never! I have been wearing the same dress since I bought it like 3 weeks ago. I guess I'll only change if I get another dress I like better.
