can you still increase them somehow and for how long? with maybe the layer books?

When you have a gold account you get 15 extra layers till it expires.

Also Ooh La Layers will give you +1 to the layer of your choosing, for 31 days.

Ooh La Layers stopped working (now it's just a book) since the new wardrobe, so there's no way to increase the total items to above 45.

Thanks Sketch. Didn't realize Ooh La Layers had stopped working.

thanks:)

layers aren't really a thing anymore - you can wear up to 30 items with a regular account, or 45 items with a gold account. it doesn't matter which layer those items are in (e.g. head, chest, bottom, etc.) like it used to. ooh la layers was relevant when you could only wear two (three with GA) items per layer, but now you can wear as many items in each layer as you want, as long as you're under the overall item limit.

Thanks Frenchi, I knew about the 30 items in any layer. I just thought Ooh La Layers still boosted it up 1 past the 30. Just hadn't tried it because 30 is more then I'll ever need. lol.
