So I noticed in cas some of the clothes I download are not in the right category, just wondering if there is a mod for this. Thanks to anyone who can help me

Which categories a piece of clothing appears in is controlled by flags in its Property Set. For CC clothing, that's initially set when the package is made in Body Shop, but it can be changed with SimPE or Wardrobe Wrangler.

Numbers of each type
Everyday 0x00000007
Formal 0x00000020
Undies 0x00000040
PJ 0x00000010
Swim 0x00000008
Workout 0x00000200
Outerwear 0x00001000

And maternity is 0x00000100

You can also add them up if you want them to show for several categories, so everyday + outerwear would be 0x00001007, and undies + PJs would be 0x00000050.

Just be aware that if you for some reason want both everyday and swim, the last digit would be F (because 8+7=15, and F is the number for 15 in hexadecimal). The rest of the numbers you can add up as if you're using regular decimal numbers. All the categories together would be 0x0000137F. This is more common for things like accessories or hair, though.

Oh my god, thank you so much guys, you guys are a great help.
