I've heard this variation: "That blouse doesn't do you justice. You know what would look good on you? Me!" I laughed, but I didn't take the giver of that compliment too seriously, haha. In reference to blouse or dress, I've also heard the 'it would look better crumpled on the floor by my bed' variation. My usual response was an eyeroll and head shake (no).
I was never good at the pickup lines. I'm just glad I met my wife at work, because I was lousy at the party/bar scene.
