Ooh, ooh, I've made a study of this, having spent about a billion hours of my working life in training sessions surrounded by the following (What's My Line?):
Badly dyed grey hair, especially 'wacky' dye-jobs. Side combs. Banana clips. Scrunchies. Loathsome tooled-leather and stick hair ?staples?.
Badly fitting suit jackets which reveal flabby bra-bulges and straining seams.
Bobbling.
More than one earring per lobe. Dangly earrings with glasses - this should be a capital crime. Especially if both earrings and glasses are in delicate 'goldesque' or 'silverique'.
Unpolished toe-nails. Horrid thick, yellow ridgy old toenails in comfy thick-soled sandals. Cracked heels. Dirty shoes. Footgloves. Swollen feet crushed into too-tight low-heeled courts.
Polonecks on unflat chests. Polyester sta-prest slacks with 10-denier knee-highs. Bare legs in winter. Tights in summer.
Frankly, a waterfall cardigan with bootcut jeans would be a welcome injection of glamour most days.
