Two-piece set: gray and black, both made of stretch material. Also, MPS black slim-fit pants with stretch. The MPS pants have some pilling. The name tag has been cut off. The gray pants show color fading from washing. They also show signs of wear such as pilling and abrasion. The black pants have been used fewer times. The gray and black pants are the same type, but the gray ones are shorter, possibly due to more frequent use. The black pants felt longer when worn. Please be sure to check the photos and consider purchasing only if you agree with the condition. Thank you for looking.
