Vintage BIG SMITH Big Smith Denim Overalls Unknown year, estimated 70s-80s Size: Unknown, M-L Double pocket, full of character Thank you for viewing. These denim overalls have a lot of character. I personally think they look great. This is just my personal opinion, so please check the photos for the condition. Year unknown. I believe they are from the 1970s-1980s. As there is no tag for the size, there is a photo with a scale at the end of the photos. Please ask any questions in the comments. Price negotiations and additional photos are possible. Thank you.
