If I'm wearing a kilt it's called a sporran and it looks normal...as long as you think a guy in kilt looks normal anyway.
Every once in awhile I see a guy in a kilt at Home Depot, but he open carries. Concealed in the sporran could work especially well if he carried a dirk and sgian-dubh as they would draw all the attention. But I conceal carry and dress like an old fart specifically so I don't draw attention for any reason.
