Weird random gloves...Where did they come from?

I was going through my Manage Households to change one of my sims who recently aged up so she was given those God awful randomized outfits by the game. As I'm looking at her outfits, I find these white fingerless gloves on her. I thought they were pretty cool so I look through CAS for them and found no trace. So how did they get there? They're not CC so there shouldn't be any fingerless gloves. Has anyone seen these gloves in their game? I'm new to sending images here in the forums so I may mess up.

Edit: The game also gave her beautiful diamond necklace that I couldn't find in CAS. I didn't screenshot that because I ended up clearing all the accessories.
