From IIChan Translation Group:
Yet another maid-tastic manga from Kaoru Mori, "Shirley" is an evocative glimpse into the daily life of winsome, 13-year-old Shirley, a maid in turn-of-the-century England. It is often compared to Yokahama Kaidashi Kikou, as both mangas feature languid pacing, atmospheric backgrounds, and a female main character who works in a cafe.

If you like YKK, have a weakness for "cute," and/or have a maid fetish, this is the manga for you. No hentai, no fanservice, zero, zip, nada. Just pure maid-tastic moemoe.
