While it’s not yet possible to sell items directly through Instagram, several fashion brands have recently partnered with third-party services to link Instagram pics of their products to retail platforms. This week, BCBGMaxAzria is harnessing the technology to sell looks fresh off the runway. This week’s BCBGMaxAzria show, taking place Thursday at 10am, is likely to draw crowds not only on site in New York but also on Instagram. To take advantage of the service, Instagram users must first sign up for a LikeToKnowIt account.
