You can just open the first spoiler you see in post #1 in this thread, there is a pic of all themed stuff.
Think thats why the thing in catalog and closet is a DRESS, and the floor decor worth 35k in the market is a GOWN.
Usually if you tap "buy" - it leads you right to the thing you need to buy. But there are some glitches from time to time that cd lead you to wrong place. If this goal's "buy" button leads you to the closet i/o market tab, i think we sd report it to devs.
