Kim Se Jeong is the new muse for Korea's popular women's casual brand Roem!

The idol-actress appears in the lookbook for Roem's new 'Signature Line' lookbook, her first activity for the brand. The line mainly features tweed dresses and sets and will officially be released on January 25 both offline and through Roem's online store.

"Kim Se Jeong's bright and positive image meeting Roem's romantic and feminine concept creates an even greater synergy for this campaign," a representative for the brand commented. "This year, Roem plans to introduce various collections one after another, starting with the Signature Line with its luxurious materials and details."

Roem is known for regularly using top idols and actresses as muses for the brand. Previous muses include Suzy, Park Shin Hye, and Song Hye Kyo.

Meanwhile, Kim Se Jeong was also recently cast as the female lead in the romantic comedy drama 'A Business Proposal.' The drama, which also stars Ahn Hyo Seop, Kim Min Kyu, Seol In Ah, and VICTON's Byungchan, begins airing on SBS next month.
