Have a good long look at QVC on the Telly,take time to find the styles you like and admire on models reflecting much your size...........taking into account that some maybe too young for comfort.
Many cater for the likes of ourselves and the prices range from cheap to expensive so you can find the ones that fit your purse.
Since they offer you a 30 day test and try...........even to wearing the garments out etc...........but will exchange,money back guartanteed,no questions asked.This makes purchasing much easier as you have time in your own home to try the individual garments on with what you may already have.
I live in the country,am house bound therefore can empathise with your situation.
This has become my mode of clothes buying over many years and by following the different clothes shows you soon learn which ones best suit both your age,fit and purse.
Well worth a try.
I also buy from Artigiano,Peter Hahn, and Franchesco catalogues.Perhaps worthy of another look.
Good luck.
