I just wear cord jeans in colours that I like, I buy 3 or 4 if I find anything good. My last 3 pairs from East lasted years until they were destroyed by a "new and improved" washing liquid that weakened the fabric. I got some lovely rich purple ones from M&S last year, with toning plain jumpers, but sadly their colours are really dull so far this year.
I certainly stay away from skirts, from old lady patterns and from most synthetic blouses - though viscose is OK.
Personally I think that it is colour that marks you out as an oldie, beige has never been for me and I don't look good in pale colours as a rule, though I do wear white Tshirts and duck egg sometimes.
My problem is always shoes, I like comfort, rarely wear heels and tend to go for simple sandals, chelsea boots or stylish lace up styles. Some laced shoes just scream old lady so you have to be careful.
I do wish that more colour was available - retailers seem to decide that colours are "in" or "out" and, at 67, I know what suits me and what doesn't.
My DH always wears jeans, T shirts and a fleece (he doesn't know that he has six identical fleeces which I wash in rotation) unless he is dressing up.
I dread an invitation that requires "smart casual" dressing - I can only do smart or very casual, nothing in between.
Is anybody else disappointed by the new online East? Its like the very worst of fussy Monsoon, without the simple lines and interesting colours that East used to do.
