The Golden Globes are a great excuse for learning a bit about men’s formalwear while picking apart our favorite celebrities.Jon Hamm always looks dapper both on and off Mad Men. Here he’s rocking a double-breasted peak lapel tux with a bowtie (a peak lapel is a broad V-shaped lapel that points up and out just below the collar). The double-breasted look broadens him; it’s a beefy, old-school masculine look that’s very much in line with his hairy face! While the beard is a little much for my taste, he looks fantastic nonetheless..Chace Crawford has on a shawl collar tux (a shawl collar has a smooth, rounded edge lapel). This look harkens back to the 1950’s and was made famous by James Dean. It’s a gorgeous, classic look that can be worn with either a bowtie or a long tie. The shawl collar is best kept on the slim side. The subtly-patterned pocket square is a nice touch..Eli Roth is sporting a notch collar 2-button tux with a long tie (a notch collar has a triangular-shaped indentation where the lapel and collar meet). The two buttons – as opposed to one button on traditional tuxes – keep it modern and understated. If you’re going to wear a long tie with a tux, make sure the width and material of the tie match the width and material of the lapel. Satin lapel equals satin tie; grosgrain lapel equals grosgrain tie. You just can’t beat the fit of this Basterd’s tux. Check out additional images here..Mickey Rourke – Mickey Rourke is a hot mess minus the hot. Although I'd expect nothing less from this gator-lovin’ rule-breaker, and in fact that’s kinda why I love him. One thing that there’s really no excuse for though in this ensemble is the watch chain. It draws your eye right to his belly…in a bad way. Final verdict: the best part about this look is his date. Girlfriend got it going on!.David Arquette presents a perfect example of very bad tailoring. A tux should fit you like a chainmail glove (see Eli Roth above). Mr. Cougartown’s pants are too baggy and long. Also, tux shoes should be sleek and streamlined – those big old oxfords belong home in his closet..While the all black look feels a little dated and a lot trying too hard, Jeff Bridges pulls it off decently well – with the exception of what appear to be rubber-soled suede shoes. Tux shoes should always be leather-soled, sleek and simple in patent leather or nicely polished calf. The rubber sole is much too casual for this look.
