1. Acid-Wash and Ripped Jeans

There's nothing like a pair of comfortable, worn-in jeans -- but this worn? In the '80s, your choices were jeans that looked like bleach had spilled on them, or jeans that looked like you tussled with a shredder. Nothing much looked good with them. And neither provided the clean, vertical lines that make legs look long.

Nowadays, we know the look that flatters almost everyone: Dark rinse, bootcut jeans that sit slightly lower than the waist.

2. Shoulder Pads

Maybe it was armor for busting through that glass ceiling. Or maybe women were trying to fit into the male-dominated workplace by looking like linebackers. Whatever the reason, shoulder pads -- the kind that added an inch or more of height -- were very, very wrong.

That doesn't mean shoulder pads should be banished into fashion oblivion. In fact, if you are round-shouldered, you might find they can square off your shoulders nicely. Look for jackets with more understated versions sewn under the lining. (Never shirts, which look too obviously padded.)

3. Flannel

It's good for lumberjacks and for people who live in chilly Seattle, but on the rest of us, flannel looked frumpy and silly. Worn open over an old concert T-shirt -- Kurt Cobain-style -- the situation got even worse.

Those looking for warm but more flattering styles should stick with this season's cozy sweaters, like vintage-inspired cardigans, adorned with a brooch, or a crocheted poncho.

4. The Dancer Look

Most of us are not professional dancers. So why did we once insist on dressing like them, complete with leg warmers, ripped sweatshirts, and braided headbands? Who did we think we were fooling? And this was just street wear. At the gym it got even worse: unitards, leotards cut waaay over the hip, and even thong bodysuits worn over biker shorts.

Still, there is something cool about that Jennifer Beals; she was on to something good. The key is to go for one element of dancer style and leave it at that. Ballet slipper flats, wrap sweaters, and chignons are classic, easy ways to convey a bit of dancer chic.

5. Tie-Dye

Like a bad flashback, this style keeps popping up at least once each decade -- and still lives on today. Fun to make at home -- not so fun to remember. The color combinations -- bright, psychedelic -- flattered almost no one. And whether you live the lifestyle or not, there's no getting away from the fact that tie-dye gives off a certain slacker vibe.

Love color? You can still wear it in a more polished way. Try unexpected combinations, like pink and red, or brown and plum. Or try to bring color in with accessories, like red shoes, a turquoise necklace, or a bright belt.

6. Bad Hair Accessories

Big hair wasn't enough in the '80s. We had to further adorn the wall of hairsprayed hair with ribbon barrettes and feathers on a clip. And those without long, overstyled hair were still in luck. They could tuck still-growing-in locks into unflattering banana clips to sport a kinda pontytail/kinda Mohawk.

Today's hair accessories (thank goodness) are a little more understated. To play if safe, stick with simple looks, like tortoiseshell ponytail holders or slim silver barrettes. You'll never have to burn photos of yourself in those.
