Jessica Alba in 3x1 Skinny Jeans

Jessica Alba showed off new blonde hair after a visit to a hair salon in Los Angeles. She wore a pair of the 3X1 W3 High-Rise Channel Seam Skinny in Black No. 5.

This American-made jean is sewn from scratch in Los Angeles and comes finished with thoughtful details and washes so subtle, you may find yourself going longer between spin cycles. The secret to this ultra-slimming, high-waist style? An extra seam on the leg which creates the illusion of mile-long leg. And this is absolutely true. I went to their store in NYC to try on a pair of the channel seam jeans and had one very attentive denim expert explain the seam to me. The seams are strategically sewn into the legs so the optical illusion of making your legs look not only longer, but also slimmer, is absolutely no illusion. (pun intended!)

You can buy the 3×1 channel seam skinny jeans at Shopbop.
