A potential lesson for all retailers - from the Lululemon leggings saga

The North American arm of the active-wear chain has been facing criticism online for selling a new collection of tights, shorts and tank tops which are too see-through.

It's paused sales of the collection through its US website, but is still selling them in its US stores.

Barclays analyst Adrienne Yih has told Yahoo, the company has been providing more new products, more often.

She says the risk from that, is having less time to test products and get feedback before they go on sale.
