Kate Beckinsale touched down at LAX airport in a subtly stylish ensemble: white blazer, silky gray top, faded skinny jeans, black suede booties, and aviator sunglasses. But thanks to her Proenza Schouler PS11 neon yellow python bag ($2,995), her travel look was taken to a totally spotlight-worthy place. Kate's latest outfit proves the power of the right purse. If you've been searching for a major pop of color, we recommend investing in Kate's exact Proenza Schouler — here are other PS11 bags to peruse. If the price tag is too steep, this Candie's neon crossbody bag ($20, originally $49) or this Steve Madden yellow bag ($78) are great alternatives. No matter which you choose, use your bold bag to inject major spunk into everything from jeans to little black dresses to your office suits.
