I don't think guys typically compliment a woman's attire unless they're interested.
Probably he was thinking "Dayumn, she's got a fine ass." But if he said that you'd think he was a perv, even though it's a perfectly natural male response to an appealing female. So instead he looks for something else to admire, finds your shoes, and mentions them. Could be nothing. Could be something. Who knows.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.
-Mark Twain
If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
-Albert Einstein
