He also found success as a painter of society portraits. He specialized in neo-classical fantasies, typically idealized scenes of women and children (and sometimes fairies and fauns) in outdoor settings.

In the need of bursaries to support himself, he moved back to London and enrolled at the Royal Academy Schools in 1893, but "his Parisian insolence and cavalier ways alienated the authorities, and in 1895 he was unceremoniously expelled." ĭespite the expulsion, Sims "had gained the confidence to start painting bacchanalian scenes of revelry, executed with astonishing flair," including The Vine in 1896, his first painting to be exhibited at the Royal Academy. Turning his back on a mercantile career, he decided to study art, and in 1890 enrolled at the South Kensington College of Art before moving back to Paris for two years at the Académie Julian. Initially apprenticed in the drapery business, at age 14 he was sent to Paris, where he learned French.

This disability was to have a profound influence on his work as an artist.
