Barwick described Glynn as unfailingly kind and generous and added: "She was profoundly bored by the pompous and splendidly contemptuous of received opinion – an unusual characteristic in a fashion editor.

[4] In 1965, Glynn married the Conservative Party politician and Anglo-Irish peer David Hennessy (the 3rd Baron Windlesham), who later became managing director of the ATV television broadcaster.

Then editor William Haley was working to broaden the paper's image and had appointed Susanne Puddefoot to supervise a new daily women's page.

Implicit in her brief was to make the paper more attractive to female readers, previously provided with occasional home cooking tips and Bond Street fashion.

Describing the fashion challenge created by the variable British summer weather in 1966, she recommended the new fashion for transparent plastic macs: "One solution to the problem of finding yourself dressed like a trawler skipper under a cloudless sky is to buy a waterproof coat that looks just like an ordinary coat, but the fabrics in which these are usually made make them much more suitable for winter than summer.

The newest solution to the sun/rain transition is the crystal clear cover up...If you find their faintly ectoplasmic look a little eerie, they share the same quality of melting into the background too.

Writing of the perils of dressing for the summer race and garden party season, she described the problem with investing in 'occasion outfits': "Look at the photographs taken at the Derby.

The weather couldn't have been more unpromising, yet there were the British ladies staunchly parading the British Special Occasion Outfit (Subsection: Race Meetings) – Sling back shoes, wind-torn Bretons clapped onto untidy damp hair, nodding and smiling away under tons of artificial pansies and draped tulle...So now, as millions all over the country are feverishly stitching a million flower petals onto a thousand flowered hats, this is a last plea for self control.

"[12] Her influence spread beyond the UK; she secured a rare interview with Cristóbal Balenciaga in 1968, the year he shut his couture house.

She was legally separated from her husband at the time of her death, from a brain haemorrhage, at St Charles Hospital, Kensington.
