I'm 50ish... Live rurally and my 'local' clothes shop are an out of town M&S, Next and supermarkets.
I do have a Debenhams in reasonable driving distance. The nearest city has lots of stores but I feel a bit overwhelmed when I visit, wander around and leave vowing to wear jeans and fleeces for the rest of my life.
What I wear now:
Jeans and fleeces are my happiest outfit and perfect for sorting out the chickens and walking the dog.
Work items which tend to be smart grey trousers with a variety of tops (I'm flinching reading this at how boring I am)
Jeans-any that bloody fit! Currently M&S dark pair best fit and I love them.
I'm a bit of a hermit (not really, but between working full time and 3 children I don't have much me time to socialises I have got away with crap wardrobe)
I'm tall, so trousers in ordinary shops are often too short or limited in availability (M&S are v good with long)
I'm curvy but not petite (wouldn't call myself fat though) -skinny jeans are not for me...
What shops should I aim for, bearing in mind that I'm not ready to dress as a pensioner but I really cannot wear clothes meant for 30yr olds.
