Fashion Addiction: I'll Share Mine If You Share Yours

A Lucky editor just asked me what the most fail-safe, beloved piece in my closet is. I'm having trouble deciding—it's actually a really tough question. As is very well documented in this column, I have big love for J.Crew cashmere cardigans: They're simple but luxurious, fit perfectly, and can be incorporated into just about any outfit. But there are other contenders too. My Grey Ant high-waisted jeans are not only the most comfortable pair I own (their stretchiness and stomach-constricting properties have made them pretty addictive) but also the most versatile. And I'm hooked on white James Perse scoopneck tees; I ended up buying three of them because I couldn't keep up with washing them as often as I wanted to wear them. Now it's your turn to tell: What's the item in your wardrobe that you can't live without? My editor and I want to know!
