Calvin Klein has released fresh photos of Korean heartthrob Rowoon lounging in their iconic brushed microfiber stretch low-rise briefs, and fans are swooning over his visuals. Since the beginning of March 2025, the American fashion brand has been dropping tidbits of the singer-turned-actor in some of their designs, including denim on denim and a tank top on briefs.
The brand's latest campaign sees the Korean star in a series of photos. In one, Rowoon wears a black shirt with CK stitched on the front with the Brushed Microfiber Stretch Low Rise Trunk in matching black; in another, he goes shirtless and wears only the Icon Cotton Stretch 3-pack Boxer Briefs.
The brand captioned the post:
“Eyes on @ewsbdi. All about maximum comfort in the new signatures. The Brushed Microfiber Stretch Trunk and Icon Cotton Stretch Brief. Do you have your Calvins on? Discover new underwear to lounge in. Now on CalvinKlein.com.”
Netizens have reacted to Rowoon’s looks in the new campaign. @walkwithrowoon stated,
“I have my Calvins on because of @ewsbdi. The best model for @calvinklein.”

Others shared similar sentiments as they described the Extraordinary You actor as the best model for the brand.
“Rowoon is made for CK. Stunning model and superb photos. Thanks to him for rising to the challenge with all the talent that characterizes him. Thanks to CK for the shooting,” @rowoonbylassie expressed.

“This is truly the most perfect model for the CK Underwear series,” @woonbest0807 added.

“@calvinkkein, he is your best model! We would love to see him adorn your ads here in the States, too! I love my CK, and all that I have purchased in the last few weeks has been because of him,” @3girls27 gushed.

More netizens commended the pictorials:
“Ro Woon absolutely nailed it!” @rowoon_th praised.

“The best model you could ever get,” @spoet04 stated.
