Sienna Miller and Mischa Barton: H&M Lovers

Always up for a day of fashionable fun, Sienna Miller and Mischa Barton both stepped out for the Matthew Williamson for H&M VIP Launch in London on Wednesday (April 22).

Held at the H&M shop on Regents Street, both Miss Miller and Miss Barton looked to be having a marvelous time as they walked inside to check out the latest trends.

The afternoon outing follows a big day for Mischa, who was busy launching her RI2K & NICA’s designer handbag line at the Soho Hotel yesterday afternoon.

Meanwhile, Sienna is coming off of a recent trip to Berlin, as she's been enjoying a break from work duties as of late.
