The night before the first big snowstorm of the year hit the first day of New York Fashion Week, Tommy Hilfiger held a runway extravaganza.

It had oversize sports jerseys! It had cropped hoodies! Jeans strewn with patches and leather shorts! Nash Grier (9.9 million followers on Instagram) was there. So was Cameron Dallas (17.9 million). Lady Gaga, fresh from her Super Bowl performance, and Kris Jenner bobbed their heads as the model Gigi Hadid and friends strode by.

Afterward Wednesday, Mr. Hilfiger hosted a full-blown festival, as he did last season in New York, complete with pop-up shops selling the collection, carnival rides, food trucks selling churros and fried chicken sandwiches, and places to create your own screen-printed T-shirts or add patches to jeans. It all culminated in a concert by the pop star Fergie, where she sang some of her biggest hits for the crowd of 3,000, a mix of industry people and consumers.

Oh, and it was in Venice Beach.
