Young women enjoy many advantages, but a sense of style is rarely one of them. Self-awareness in matters of dress only tends to come with middle-age, which is why PR Hannah Moore is something of a rarity among her contemporaries. Although only in her mid-20s, her wardrobe indicates a discriminating eye and a keen understanding of what she can wear to best advantage.

Her own advantages include a face of gamine charm; she is most frequently compared to actress Winona Ryder, with whom she shares sallow skin colouring and glossy, dark brunette hair. Among her very best features are deep, lustrous eyes and a broad, enticing smile. Many other women her age are as good-looking and possess as excellent a figure. Almost none of them, however, can be said to employ these as well as she does.

The essence of Hannah Moore's personal style is seen in her choice of simply-cut clothing. A modernist, she conforms to Louis Sullivan's dictum that form follows function and will never be found wearing anything unnecessarily fussy, opting instead for items which are almost puritanical in their understated character.

Among her favourite styles are scoop-neck shift dresses to the knee worn with a cardigan thrown over the shoulders (and buttoned at the neck) as well as crisply-cut dark skirt suits. She is the ideal client for Irish designer Marc O'Neill, whose spare, tailored clothes she can regularly be spotted wearing.

Unusually for a working woman, she tends to avoid trousers unless these are cropped Capri pants for the weekend. Bright colours and jewellery are both kept to a minimum. If there is a single element of frivolity in her appearance this may be seen sometimes in the choice of footwear - backless kitten-heel mules or embroidered pumps from Paul Smith. Her style shows that it is possible for a woman to be both spartan and seductive.
