A new year calls for a new top. One that is strapless, equal parts edgy and elegant and day-to-night wearable. Designers from Lanvin to Isabel Marant to are serving up different iterations of the historically sexy bustier, and this spring I'll be tempted to try all of them. For starters, I'll work one that's a bit loose and flowy like this . Then I might up the ante in this leather (30% off) with sleek black wide-leg pants. For a night out with the hubby, you could catch me in this nicely-priced lace , under a structured blazer, with my favorite pair of jeans.
