Welcome Awks! Your wedding dress sounds like mine, also 1989 and also with bows on the shoulder. My hair is naturally curly so the blow dry made it look like a perm (but it looked good then).
When I started uni my look was quite sloaney. I had a copy of US Vogue Teen which was full of preppy outfits, which I used as my inspiration. So, kilts, shirts (upturned collar ;) ) and lambs wool sweaters. I also had a duffel coat and college scarf.
University (and a part time job) helped change my style but I was quite chameleon -like. I met DH as a student and I can't remember what I was wearing but it was probably jeans and a sweatshirt or one of my more experimental outfits concocted from my mum or dad's cast-offs or bought from a vintage shop.
When I started work, I embraced the yuppie (remember them?) look and devoured the Next catalogue. I wish I had kept the very first one with its fabric swatches. I felt so grown up in my work clothes.
Becoming a sahm mum was, style-wise, not great. I put on weight, money was tight and I lost confidence. When I went back to work, about 13 years ago, I panicked and bought some boring outfits (badly fitting suits, skirts the wrong length, bad colours). Oh and with my hair too short, the curls made it look like I'd had a wash and set!
Nowadays, I put on and lose the same stone regularly, but I have a much better idea of what suits me. I like my work clothes: typical would be a Me& em ruched dress with jacket and shoe boots and, because I don't wear them all the time, I am happy in jeans at the weekend (and they are better jeans).
After years of straightening my hair, I am letting the curls back, but as it is longer, it is wavier and so I am avoiding the permed look. Since discovering this thread, I buy less but better e.g. more silk and less polyester. I also have more confidence.
Sorry for another long one, but I also found it cathartic.
