Most girls can agree that every closet needs a wide selection of dresses to pull from—after all, there’s parties to attend, cocktail hours, business meetings, and plenty more in the day-to-day life of a modern girl. For that reason, H&M is introducing the By Night capsule collection, a 20-piece lineup of dresses for every occasion. The focus behind the collection—to create glamorous dresses with a “rock and roll edge”—has resulted in a slew of oversized ruffles, lace trim, metallic beading, animal prints, sheer layers, and sequins, all in a modern palette of black, gold, silver and green. The H&M By Night capsule collection will arrives in H&M stores in September. In the meantime, fans can look forward to three new capsule dress collections arriving for Spring 2011.
