What: Black Halo Belted Bouquet Dress, $366
Why: While plenty of celebs sport Black Halo dresses, none seem to have made the same spalsh as this super chic design worn by Mandy Moore on the November cover of Lucky. Since then, we've watched the dress fly off shelves faster than retailers can restock, and, two months later, this remains an incredibly hot best seller.
What makes it so special? Aside from the starlet endorsement (Mandy really did look fab in it), we think women flipped for the sleek lines that make this style as equally appropriate in the office (just add a cardigan) as it is for a hot dinner date (shed the sweater). It also rocks the high-waisted look and pencil skirt bottom, which makes it both completely on-trend with a classic shape that keeps coming back in style. If you can get your hands on one, we think this little number could be something you'd continue to wear for years to come.
