BUR #6310 has been approved by @evazion.
remove alias floppy_sleeves -> oversized_clothes
I struggled to find any discussion or the BUR where this was aliased, but I think this alias should be removed. Floppy sleeves are just sleeves_past_fingers, and not always due to the clothes being too big (post #4578945 looks like only the sleeves are too long). Common examples where sleeves that are too long but the rest of the clothing isn't oversized per se is Komeiji Koishi (post #4578476) and Mononobe no Futo (post #4440495). Sometimes the character is removing a normally-fitting long sleeve jacket/coat/shirt/sweater (e.g. post #4617668) and the sleeves flop past the fingers (more so than sleeves_past_fingers), or it's off_shoulder. Oversized_clothes should be added manually by the tagger if the clothes are visibly too loose.
If this unalias passes, I'll create a new BUR for floppy_sleeves to imply sleeves_past_fingers (unless it can be added to this BUR).
