I am also selling a bow tie and a shirt (90cm) that I purchased at the store at the same time as these pants. (I wore them together when attending a wedding. I don't think they were a set.) If you purchase them together, I will offer a discount, so please comment before purchasing. (The bow tie listing is a little further down than this listing. The shirt is further up.) I think these can be worn for both formal occasions and everyday wear.
