Cotton overalls from Argue. I wore these for about two seasons, and then stored them at home. There are no noticeable stains, but please refrain from purchasing if you are overly concerned about minor details (there are some slight scuff marks). Also, the buttons tend to come loose, so I have reattached them more securely. If you are concerned, you may want to reattach them again. I would appreciate it if those who are not concerned would consider purchasing. Thank you.
