A part by is a Japanese women's fashion brand launched in 2006.

e/rm is a brand specializing in loungewear and sleepwear, derived in 2020 from apart by lowrys, the predecessor of A part by. While A part by focuses mainly on clothing for going out, offering styles for occasions ranging from ceremonies to everyday wear, e/rm extends its scope to time spent at home and the sleeping environment, offering products that emphasize unpretentious design, functionality, and feel against the skin. Centered on “Room 7 to 7”—loungewear for 7 a.m. to 7 p.m. and sleepwear for 7 p.m. to 7 a.m.—the line extends its parent brand’s lifestyle offering to time spent at home.
