Lululemon Founder Resigns; Victoria Beckham's Wedding Tiara Fails to Sell

And Mango launches a plus-size line.

Lululemon Founder Resigns as Chairman: Chip Wilson, the outspoken, fat-shaming founder of Lululemon, announced his resignation as chairman of the company on Tuesday. Wilson, who is best known for his comments that some women's bodies simply don't work for Lululemon's products, will be replaced by lead director Michael Casey, who will assume his position come June. Unsurprisingly, AP reports that "analysts that follow the company believe Wilson alienated some core customers and potentially opened a door in the lucrative market to rivals like Nike, Under Armour, Athleta and others." The company also announced that Laurent Potdevin, former president of Toms Shoes, would be replacing former CEO Christine Day, who resigned in June. [AP]
