MILWAUKEE — Oh, the sweater designs are frightful, but the parties are so delightful. So if you've got one to wear, let it show, let it show, let it show.

If your grandmother ever gave you a cheesy holiday sweater that you never thought you'd wear, be grateful — it's a hot fashion item now. Gaudy Christmas sweaters have become all the rage. Ugly-Christmas-sweater parties are so popular that thrift stores and specialty retailers are making sure the kitschy clothing is in stock, and enterprising entrepreneurs are cashing in.

One Chicago couple say they've sold more than 3,000 sweaters this year from a website they started in 2008, while a pair of Milwaukee siblings expect to clear a $5,000 profit from a new site they launched just last month.

Jack McCarthy, 17, and his sister sell sweaters scavenged from thrift stores and yard sales for anywhere from $19 to $45 on

"People just seem to love outdoing each other in ugliness," McCarthy said. "The key is, you want something that's tacky in a good way. You don't want ugly like boring, you want something like a piece of art. Something that might look good if it weren't on a sweater.

"Like it might be a good Christmas decoration, but once you put it on yourself that's where it becomes ugly."

The sweaters' popularity reflects a common fashion arc: Something trendy goes out of style, only to become cool again decades later. Some people speculate that loud sweaters evoke fond memories of holidays past. Others say it's just an expression of holiday cheer.

Either way, when it comes to Christmas sweaters, uglier is better. Bright and mismatched colors are a plus, as are sequins, beads and fringes. But the clincher is graphics — winter scenes busy and intricate enough to make the viewer cringe.

Emily Bell knows ugly when she sees it. The 30-year-old from the Milwaukee suburb of St. Francis was determined to win her friend's ugly-sweater contest. So she scoured thrift stores with one strategy: If a garment could be called tasteful, it wasn't good enough.

For less than $10 she bought a blue blazer covered in oversized stars, trees and snowmen, along with a bright red sweater showing a Christmas tree trimmed with bulbous red ornaments.
