Great for a costume, but not for every day
Color: White, Size: Medium
I'm not sure what I was really expecting, but these pants made me feel like I was in the song zoot suit riot and/or Dick Tracy was trying to find me. They honestly just feel very costume-ish as opposed to being something dressy. I couldn't see myself wearing these to a job interview, which is kind of my standard for what qualifies as "dress clothes." However, they do fit quite well in the waist the and down the leg. I have a wide variety of clothing options, but I even find it difficult to pair anything with these pants.
