Don't think mauve, but the color of rustic pink is more of a gray-ish, muted champagne pink. Don't think too pink, because it's more nude than that. But definitely not coral either. What do you think the color of rustic pink looks like? Here are several gowns from Elie Saab that would make for stunning matron-of-honor dresses or gowns for the moms to wear. There's also a flirty cocktail length dress that would be appropriate for guests of the wedding to wear also.
Earlier, I shared a card about Elie Saab's 2012 flashback to coral. Click here to see those dresses.
