LOS ANGELES—MOCA Store presents a pop-up shop with Los Angeles–based design and accessories studio Building Block. Started in 2011 by sisters Kimberly and Nancy Wu, Building Block discards the conventions of luxury by magnifying the essential and omitting the excessive. The result is a line of beautifully crafted, minimalist handbags and accessories that hold cult status among fashion influencers and the design obsessed. Building Block has designed two exclusive pieces for MOCA Store that will be launched in-store on April 26. For a sneak peek, follow @mocastoreson Instagram.
