Clothing never runs out. As you get to higher levels in the game, you'll be able to see more and more clothing.

That's why you see higher levels with clothing you can't see in Nine's.

Also, there are VIB (paid memberships). VIBs also have clothes that you can't see in Nine's.

Additionally:
In the bottom left corner of the page, there is a list of the most recent announcements. Always read those so you know what's going on with the game.

In the last announcement, the designer listed what levels each new item became available: Crooked Party

Is there any kind of breakdown? I've seen that you unlock some at level 5 and 20 but what about in between?

Thank you! I just got to level 10 (I was on 8 for a couple days) and i see some new items

one more question... i know that new items come to Nine's quite frequently (hipster stuff coming Monday I'm seeing) but what happens to the items that just came out the week before? Do the outfits that were just featured go away once new featured stuff is in?
