Anything that could be described as a 'blouse'.
Anything made of that viscose/crepey type of material.
Most patterns.
Colours that are slightly 'off': mauve, turquoise,mustard, petrol blue... I think of them as Fat Face/White Stuff colours.
Tunic dresses.
Dresses and leggings.
Ballet flats, however they're worn. Ditto Mary-Jane's.
Anoraks worn as everyday coats, as opposed to for hiking etc. Ditto walking boots.
Cap sleeved t shirts when you're rotund of arm.
Patterned handbags or tote bags or umbrellas.
Brightly colored tights. Low denier tights. Any tights that aren't opaque and basic colours!
The type of themed clothing that Seasalt/Joules et al sell e.g. seaside woman/country cottage woman. Toast is bad for this as well. All the pinafores and dungarees and Breton stripes. It's contrived and it's become a woman-of-a-certain-age stereotype.
Big handbags full of stuff.
Doc Martens, especially the coloured ones.
Wearing glasses, except sunglasses.
Brighter pink lipsticks and nail varnishes.
Sportswear as everyday wear unless it's that Varley-type athleisure look.
Round-neck buttoned cardigans. Waterfall cardigans.
Chunky beaded jewelry. Brooches.
Radley bags.
Chiffon scarves.
I've obviously given this way too much thought! I helped my mum (70s) sort her wardrobe when she downsized and these are the conclusions we reached.
