Before M.Nii, Moore came up with the name of Abercrombie & Fitch’s Hollister line and helmed Pop Studios, which crafts compelling brand stories for fresh concepts. Up next for the designer? A collaborative collection with Gap for the upcoming fall season.   (Kirk McKoy / Los Angeles Times)

Though M.Nii is primarily a menswear label, the line also offers a small selection of tanks, T-shirts and shirtdresses for women.  (Kirk McKoy / Los Angeles Times)

Moore poses with a surfboard in the M.Nii studio. The M.Nii brand was inspired by the original M. Nii, a tailor shop that made custom swim trunks for surfers in Hawaii.  (Kirk McKoy / Los Angeles Times)

Although the brand has now expanded, the first collection consisted of variations of twill surf trunks. Pictured here, a pair of “Canyon Bloom Drowner” trunks in Seventies Blue ($163, www.mnii.com).  (Kirk McKoy / Los Angeles Times)

M. Nii includes pockets in many of its swim trunks for surfers to put wax in. Pictured here, “The Waxer” in Indigo ($195, www.mnii.com).   (Kirk McKoy / Los Angeles Times)
