Instagram didn't need a filter at Marc Jacobs. The first half of the runway show was lighted in a sepia tone, presumably so that the audience could focus on the details of the clothes. (The lights were taken up for the second half of the show--every model re-walked the circular runway so that we could see the looks in technicolor, too.) It doesn't matter which season, or whether or not we're blown away by the clothes, Marc Jacobs is time and time again the most wonderful moment of New York Fashion Week. Falling on Valentine's Day, it was the ultimate fashion love letter.
