Gentlemen, do you have any own material?

It's always worth to look up when walking around Edinburgh, yesterday it was the clouds, today it's another example of good old street advertising from the times when people still used apostrophes in the correct places - "Clothing cleaned, altered & repaired. Gentlemen's own material made up."

I hope the people living in the flat which is on the same level as this ad didn't think I was photographing their windows or I'll be charged with stalking...
