Mrs Dumbarton was the stringent Miami Modes department supervisor and direct superior of Elsie Tanner and Dot Greenhalgh at the clothing outlet in the early 1960s. Mrs Dumbarton was a stickler for timekeeping but despite Elsie's complaints about her bossiness, Dot pointed out that if Elsie ever made it to work on time she would probably die of shock.
In October 1962, Elsie "borrowed" a dress from the shop to wear to Jack and Annie Walker's silver wedding anniversary, intending to return it without Mrs Dumbarton noticing. Elsie was delayed getting it back as she had to have it cleaned after Leonard Swindley spilled wine over it at the party, but while Mrs Dumbarton noticed the dress's absence, Elsie managed to get it back before her suspicions were aroused further.
