The lingerie and apparel brand owned by American Eagle Outfitters is Aerie.
American Eagle launched Aerie as its first major sub-brand in February 2006. The name originally emphasized lingerie and intimates, including bras and underwear, but the range expanded into sleepwear, loungewear, activewear, swimwear, accessories, and other casual apparel.
Aerie began as merchandise sold through American Eagle stores and online. Its first standalone store opened in August 2006 in Greenville, South Carolina, followed by additional test stores. That format helped turn Aerie from a department within American Eagle into a recognizable retail brand of its own.
A common mix-up is confusing Aerie with Victoria's Secret or PINK, which are separate brands. Aerie is especially associated with its #AerieREAL campaign, introduced in the 2010s, which promoted unretouched models and broader representation. American Eagle Outfitters remains Aerie's parent company, while Aerie's own assortment reaches well beyond traditional lingerie.
