I basically use Subeta as a huge dress up doll website, I seriously love making HA's and love that this site lets you build them using all the items on site - but since there are SO MANY beautiful items I find it hard to stick to a theme throughout building one.
I went through each layer I would typically use making an HA using an RNG to pick a page and then selected an item (or two or three) from that page so I could stop myself from getting distracted by all the options, this is what I ended up with!

I'd love to see some more if any of you are interested in playing around with the idea. I guess a true RNG build would be picking a page number and then picking the item number, too but I was hoping to make something somewhat cohesive and themed haha.
