His painterly subjects ranged from the allegorical, figurative, and historical to the theatrical. He admired the style of Jean-Louis-Ernest Meissonier, the French classicist painter. Hughes was preoccupied with the refinement of the presentation of his subject, the depiction of idealized feminine beauty and the tribulations of romantic love. In a 1902 article in The Magazine of Art writer Marion Hepworth Dixon commented on Hughes's "dexterity of hand, the extraordinary facility with which he renders the different surfaces of stuffs, woods, and metal, together with the agility of his outlook and the verve and spontaneity of his eighteenth century designs." Hughes's submissions to the Royal Academy included works carrying such titles as "Temptation", "Fate leads the willing, and the unwilling drags" and "The Road of Love".
His collections
Talbot Hughes amassed a collection of over 750 historical costumes and accessories, dating from c.1450 to the through the 1870s, which he used as studio props. In 1910 he sold a small collection of bags to the Victoria and Albert Museum and also donated individual items, including an 1820s frock coat. In 1913, when Hughes decided to put the rest of his collection up for sale, he was offered £5,000 by an American department store who wished to donate it to the Metropolitan Museum of Art. Rather than send his collection abroad, Hughes instead sold it to the department store Harrods in London for £2,500, where it was displayed for three weeks to advertise the store's own range of women's contemporary fashions. After this period, Harrods transferred the collection by donation to the Victoria & Albert Museum, the result of negotiations by the then Director of the V&A, Cecil Harcourt Smith. The collection is still kept at the V&A. Talbot Hughes continued to donate individual items to the Museum up until 1931. Also in 1913, Hughes published his book Dress Design: an account of costume for artists and dress makers, illustrated by the author from old examples. In 1928 the dealer Philip Rosenbach bought Hughes’s collection of 450 miniature portraits. In 1988 the Rosenbach Museum & Library in Philadelphia, USA, mounted an exhibition of 30 of his Spanish portrait miniatures.
