Want to look ten pounds thinner? Try wearing a shirt with vertical seams.

Ted Baker's cotton "Webeka" shirt looks like your run-of-the-mill point collar dress shirt, but on closer inspection, you'll see that the front and the back have the smart detail of trimmed seaming.

Like vertical stripes that make you look tall and thin, seaming on a garment gives the illusion of length, so even though you may have gorged on a lunch of beer and pizza, you'll still look svelte. ($110 from Bluefly.com)
