VANCOUVER, Canada — Canadian apparel maker Lululemon Athletica Inc on Tuesday named Calvin McDonald as its new chief executive, replacing Laurent Potdevin.

McDonald joins from LVMH's cosmetics retailer Sephora, where he was head of the Americas region, and will start in his new role at Lululemon on August 20.

Lululemon has been looking for a new chief executive since February after Potdevin abruptly resigned for falling short of the company's "standards of conduct."

McDonald joins Lululemon as the company, which turned women's yoga wear into mainstream fashion, looks to expand its online presence and offer more men's wear to better compete with the likes of Under Armour Inc and Nike Inc in a cut-throat sportswear market.
