The pink BCBG dress is so adorable and is surprisingly also affordable. It's only $238.00 and is very reminiscent of Sienna Miller's white Marchesa except way not as pretty. Look, I'm not even going to pretend like these dresses are comparable other than the fact that they both have giant flowers on them. We all know that when we put the cheap comparable on our bodies, no matter how close it came to the real thing never looks anything like the awesome expensive version. And sometimes even gives you a rash and blisters. But, then again, we're not Sienna Miller and the BCBG dress is not Marchesa. You won't look like a white satin fairy princess in the BCBG, but you also didn't spend $5,000.00. So, you get what you pay for, and in this case, it's a cheap Sienna Miller.
