It's pretty well-known that Lulu's sizing skews particularly small. With a size two equating to an XXS, everything seems to be well-tailored to a petite frame. Even the svelte, tall models on its website wear a size six, meaning sizes two and four are really, really small. My favorite finds? The Lululemon Wunder Train High-Rise Tight ($98) (I own these, and they're great!), which hit perfectly at the top of my feet as full-length pants. The brand also offers free hemming on all its products, including tops, so you can adjust to the right length.
