Alright if you've placed all the figuremap and figuredata in the correct places and have the actual clothing.swf placed in the production folder then the only thing I can think of is inside the figuredata, have a look and see if the
selectable="0" is set to 1, habbo mostly keep it as 0 because they have clothing in the catalog now.
Example, it should look like this if it doesn't then copy it for the clothing that you're adding.

Sellable="1" = Can be sold in the catalog.
Sellable="0" = Can't be sold in the catalog.
Selectable="1" = Can be selected in clothing editor.
Selectable="0" = Can't be selected in clothing editor.
