Home-runs, all of them! The four stars selected for this week's Look of the Week all hit it out of the ballpark when it comes to their red carpet ensembles.

Selena Gomez was a gorgeous lady in red at the March 14 premiere of her new controversial movie Spring Breakers in Hollywood. The Disney graduate wore a glamorous, flowing, scarlet Reem Acra gown with beaded illusion panels. Drop earrings by Lorraine Schwartz completed the ensemble. The sophisticated dress was a big departure from the 23-year-old actress' bikini-clad Spring Breakers look.

Girls star Allison Williams, 24, arrived for her interview with The Elvis Duran Z100 Morning Show in NYC on March 12 in a fetching, black, fit and flair Red Valentino dress with scalloped edges. The star often opts for more conservative and mature outfits, but this dress is a nice balance of modesty and youthfulness.

The always stunning Zoe Saldana hit The Hollywood Reporter and Jimmy Choo 25 Most Powerful Stylists Luncheon on March 13 in West Hollywood in a chic, ready-for-spring red and white toile Carven dress with cutouts at the waist. Jimmy Choo ankle-tie sandals with tassels finished the look. The actress was on hand to support her stylist Petra Flannery, one of the luncheon's honorees.
