Jessica Alba spent quality time with her girls in LA and all the while showed us the simplest way to amp up our boyfriend jeans for Summer. How so? By pairing a black camisole with her Citizens of Humanity denim ($238), which she cuffed at the bottom. We dig the juxtaposition between the fitted top and baggy bottoms. The stylish mom then added a few key pieces to round out the laid-back look. She wore a black straw hat on her head, threw on a deep red Marni crossbody bag for a hint of color, then finished with black strappy sandals. To give your own boyfriend jeans a fresh treatment, just follow Jessica's lead and match them with a fitted camisole — in any color! — and add your favorite accessories to finish.
