The last time you thought about donning a pair of denim overalls, you were probably working out what to wear to that Alice in Chains concert.

But the humble coveralls — which last clomped into vogue during the grunge era — are easing their way back into high fashion.

No mystery why: Grunge is back, Pearl Jammers, in all its plaid flannel, Doc Marten-shod glory.

Laurie Pike, Los Angeles magazine’s savvy style director, first clued us into the reemergence of the hayseed staple in the November issue of the magazine, positing, “when overalls get the runway treatment, a solid trend is afoot.”

She cited Ralph Lauren and Yves Saint Laurent among the high-end brands who’ve flirted with the one-piece recently, along with sportswear labels including Volcom and Joe’s Jeans.

I think overalls are adorable on tall-and-thin gals. But if you’re at all busty (like me), you might want to sit this trend out. Because there’s nothing cute about sporting a mini pup-tent on your chest.
