I've got a wedding to go to this Saturday evening(7:00 pm). It's being held at my friend's home(in the backyard) in the small town we grew up in. The suggested attire is "business casual." What would you suggest I wear? I would like to avoid khakis if possible. I was thinking that maybe I could wear my (very) dark blue jeans with dark stitching(matches the fabric color) that does not "stand out," along with my black Miu Miu loafers, a light blue dress shirt(open-necked, without tie), a 3-button single-breasted black Ferragamo sportcoat and perhaps a black single-breasted vest which matches the sportcoat. Thoughts on this combo? One note: this black sportcoat is my only sportcoat.
