Dudes, let this be a warning to you. This is summer; it is hot. No matter how cool your favorite spring jacket is -- even if it cost $250 and you only got to wear it like three times -- you can't make it work in the sweltering heat.

If you don't believe me, just look at Jack. The poor guy's hilarious red carpet antics left him a little, erm, moist by the time he made it in front the cameras. Do not less this happen to you. Arm yourself with a bad ass antiperspirant, and then act casual. Unless you're working or doing manual labor, nothing is less sexy than a guy with pit stains.
