Featuring rich jewel tones, vibrant prints, and sumptuous brocades and furs, Oscar De La Renta‘s Fall 2010 collection is making us count down the days until the end of summer. But have you ever actually seen the work that goes into the making of a designer’s line? The exclusive video above, which offers a rare behind-the-scenes look at de la Renta’s New York atelier, provides a glimpse into the process of taking an item from the sample room to the runway; even those who sat front row at the fall show didn’t get this good of a view! Plus, check out a few of our favorite looks from the collection after the jump.
