I still love dressing up from time to time, if only for the sheer relief of taking it all off! But mostly, I agree with the rest of you, especially; polo necks or crew necks, which provide a sort of shelf effect. And I HATE:
Polyester in any form
Anything beige
Embroidered t shirts in said polyester
Elasticated waist trousers ditto
Waterfall cardigans
Knee highs (shudder)
Long sleeves (and they are ALL too long)
Nighties
Better stop now.....oh, but also - fleece jackets, unless they are hip length.
(Also hate old guys getting it off on any mention of stockings and suspenders.)
