H&M, the popular apparel retailer specializing in “fast fashion” clothing, plans to open its Boulder store next Thursday, officials for the Swedish retailer confirmed. 

Hennes & Mauritz AB, which does business as H&M, signed a lease earlier this year to open an 18,000-square-foot store at 1755 29th St. at the Twenty Ninth Street mall in Boulder.

The retailer known for its fast fashion clothing — inexpensive versions of current and trendy designer apparel — has had a successful string of store openings in Colorado. 

A line of 900 people wrapped around the Denver Pavilions store when it opened in late 2011 and more than 200 people waited outside the FlatIron Crossing H&M on its opening day in August 2012.

There likely will be similar crowds in Boulder.

In an effort to promote its opening day at Twenty Ninth Street, the retailer is offering a deal in which the first 100 shoppers in line next week will receive up to $300 off their entire purchases. 

The Boulder store would be H&M's fifth in Colorado and represents another high-profile retailer landed by Twenty Ninth Street within the past year. Specialty grocer Trader Joe's last year picked the retail center as the locale for one of its first Colorado stores.

The Trader Joe's store is under construction and is expected to open in 2014.
