Heidi Montag’s Wedding Dress By Monique Lhuillier. We all know that Heidi has great style and for her wedding gown she choose one by Monique Lhuillier. The dress was from Monique Lhuillier's spring 2009 collection. The gown was made of silk organza and featured a embellished motif at the center. (which is one of the reason I believe Heidi chose this dress) The gown also featured a drop down waist with peacock feathers and retails for $7,500. While the ivory sash goes for $2,500. Quite a pricey piece but Heidi really made the dress her own by adding expensive necklaces and bracelets to make the embellished center of the dress pop. Overall love the look and love the gown.
