How do I match accessories to theme in Contest Hall?

I understand Appeal and Popularity, but the mechanics of Theme are confusing to me. Wiki and contest instructions say that you should use accessories that match the theme. But how? Which accessories 'match' to 'the created' or 'the shapely'? Is there a list somewhere that says which accessories match the theme? I don't get how it's calculated.

I use the list on Bulbapedia and always score high, though I'm not really sure where the site-made accessories (the Halloween stuff) fall since they aren't on there. As far as I know there isn't a list like this on the pokefarm wiki. https://bulbapedia.bulbagarden.net/wiki/Accessory

Thank you, Edgy! <3 Exactly what I've been looking for. Yeah, I've not been able to find anything like that on the pokefarm wiki.

Here's a post from the PFQ Guide to Contests forum thread. https://pokefarm.com/forum/post/4301820 It has all the info you need to know about which accessory items work towards which contest theme. The rest of that thread has other Contest info and is very helpful overall.

Thank you, Goatlady! <3 That is an overall helpful guide. I'd looked about in the guide section before, but somehow missed it. Glad I know about it now!
