I'm Northern too (Manchester to be precise) 52 years old, my style is similar to yours. I wear mainly Joe Brown or Joanie Clothing dresses (they suit my shape) with either my Office boots (brown suede, calf length, chunky heel) or trainers (Vans, Puma, Nike, Reebok.. they're a bit of an obsession of mine atm) and either cardigan or denim jacket.
I've worn a variation of this outfit since around 1988 when 18yr old me found a beautiful, Laura Ashley style, lace collared dress in BHS and wore it with my DM's and leather biker jacket.
Much like yourself, I'm not really bothered what's in fashion, I found my look many years ago and have more or less stuck with it ever since.
