While strolling the streets of NYC with Suri over the weekend, Katie Holmes wore this J. Crew floral button-up blouse ($150) with a pair of wide-leg lightwash Goldsign jeans, creating the perfect '70s-inspired daytime look. She finished her ensemble via oversized square metal sunglasses, off-white shoes, and a tan bag. While we love the way Katie styled her floral blouse — here are similar wide-leg jeans by Marc by Marc Jacobs ($228) to re-create her outfit — it would also look fabulous with a pair of black shorts or a denim skirt. You can also dress it up with leather pants and killer heels for night, or tuck it into a pencil skirt or wide-leg trousers for a more professional feel at work.
