A “crystal constellation” cardigan ensemble worn by First Lady Michelle Obama in London last Wednesday has boosted sales and prompted a 200-person waiting list for popular retailer J. Crew.

After photos of Mrs. Obama sporting the $298 outfit during a visit to Maggie’s Cancer Caring Centre surfaced online last week, the ensemble was sold out by 10 a.m. that morning, and her $258 “dazzling dots” skirt was “virtually gone as well,” according to The New York Daily News.

This isn’t the first time the First Lady’s fashion sense has prompted a shopping frenzy for J. Crew lovers. When Mrs. Obama appeared on The Tonight Show with Jay Leno in October wearing $340 worth of J.Crew pieces, the store’s site had a 64% increase in traffic for the day.
