A men's pop-up shop for Calvin Klein Underwear will open at Zero Base in Omotesando from April 21st to 27th. The first floor of the two-story store will showcase the brand's latest men's underwear, "Intense Power," in a gradient colorway featuring contrasting colors on the logo and waistband. The lineup includes hip briefs, boxer briefs, trunks, and low-rise trunks. These figure-hugging pieces are made with stretch cotton for comfort and freedom of movement. They also feature intricate details and technical fibers for a comfortable feel and breathability. Additionally, Calvin Klein is currently running a social media campaign called "#mycalvins," in which shoppers are invited to post photos of themselves wearing the brand's items. The brand is also encouraging shoppers to participate.
