Trendy apparel retailer American Eagle Outfitters Inc on Wednesday posted a 2.8 per cent fall in monthly same-store sales at its namesake shops and announced a key appointment.

The Pennsylvania-based company said September consolidated same-store sales, which include its Bluenotes/Thriftys banners in Canada, fell three per cent year-on-year.

Total sales at its 900 stores for the five weeks ended October 4 climbed 7.9 per cent to $122.1 million from the year-ago period.

The retailer also named Henry Stafford as its new vice president and general merchandising manager of American Eagle's men's division. He replaces Fred Glover who was recently appointed president of its Bluenotes subsidiary.

Stafford was most recently at Old Navy where he held the position of divisional merchandise manager of men's active and tops divisions.

Co-CEO, Roger Markfield, said: "We are extremely pleased to welcome Henry to American Eagle. He brings substantial talent and experience to our company, which perfectly complement our strong men's team.”
