We've all had that sinking feeling, the "What was I thinking?" moment when we look at an old photo and can't believe we appeared in public looking that way.
As we start a new decade, let's take a look at some recent fashion and style trends — those worth keeping and the ones whose searing images cry out for a bonfire.
The single worst idea in many decades was the notion that grown women should show off their naked stomachs.
Low-slung jeans gave even the skinniest women an unsightly muffin top spillover.
Pairing these with a crop top that stops above the belly button has fashion disaster written all over it.
The proliferation of jean options in the last decade is a huge and welcome development for women of all ages. But at what cost? Besides the bare belly problem, can any pair of dungarees be worth $400? Nope.
Pee-wee Herman suits
It wasn't just women who went bad. The shrunken men's suit popularized by designer Thom Brown was hard to take seriously. But Jay-Z and other celebrities known for their immaculate menswear are signaling a turn to more formal dressing for men. And that's a good thing. Jeremy Gutsche, founder of trendhunter.com, predicts we'll see men's "half formal dressing," sprucing up traditional business casual with blazers, bow ties and the like. But khaki pants with blue shirts are here to stay. Alas, forever.
The Olsen twins could get away with the "bohemian" (bag lady) look — appearing as though they are being devoured by their droopy clothes and massive purses. "They can look bummy because they're not bums. When you're billionaires, you can look any way you want," says Kathryn Finney of budget fashionista.com. For the rest of us: Forget it. More streamlined fashion with artisan touches such as embroidery, beading and fringe is a better choice in 2010.
