How do you add a tile to your HA when you want to submit to a contest?

You add it on the regular subeta site, in your wardrobe. In the Outfits tab, you click on the outfit, and then on the pencil icon on the top of the page. You can change the title of an outfit as you're saving it, but also of all your previous saved outfits. That really helps to filter by name, when you have several outfits per theme, like summer, fall, or by colour etc ^_^

Thanks much, very helpful <3
