Someone from Boston, Massachusetts, USA, asked via a search engine, “is wearing white socks in cowboy boots wrong?”
Unless this question was entered by a female, who may wear a skirt or blouse with cow “girl” boots… then there could be a legitimate concern about socks being visible with boots. But since the question was specifically about cow “boy” boots, then I think the assumption that the questioner was male is correct. (You won’t believe how many “cowgirl boots” questions I see!)
For more information about socks to wear with boots, see this post.
Life is short: wear socks with boots. Color doesn’t matter.
