Eager to check out new duds and be a part of helping the planet, Penn Badgley and Victoria Justice attended H&M's Exclusive Conscious Collection launch party on Thursday (April 4).

Looking stunning in a little black dress, the "Victorious" actress worked the red carpet as she hosted the West Hollywood event, while the "Gossip Girl" actor kept it casual at the New York City festivities.

Eager to have her fans drop by, Justice tweeted earlier in the day, "Hey guys, I'm in West Hollywood at H&M doing a meet and greet. Come down and say hi.”

Keeping with their sustainability efforts, H&M had their garment collection boxes at each gathering. The retailer is now allowing customers to drop off unwanted clothing in their stores in an effort to help textile waste.
