Good catch - I wonder how long this has been broken. There's an error in the mod's list file - it has 2 elements (corset and bondage top), but gives them both the same ID. So the corset which should have been ID 2 got saved as ID 1, and on load it loaded 1 - which is the bondage top.
Here's a link to the repaired mod:

Put the repaired zipmod in mods\mymods, and fire up kkmanager and disable the original version which is in Sideloader Modpack\TM. You'll need to load the corsets again and re-save your cards so the cards get the new ID, but then they'll actually reload with corsets.
