This is the wedding dress that Robin Scherbatsky (Cobie Smulders) was wearing for her and Barney’s wedding at the start of this week’s episode of How I Met Your Mother.  Its a pretty dress with a corset front and a twisted mesh detail from the bust to shoulders/sleeves.

It is the Monique Lhuillier Addie Wedding Dress.  Contact Monique Lhuillier for information.
