I also cannot bring myself to go back to that 80's style. Even though I'm skinny, I'm short and my butt is bigger than the rest of my and I look ridiculous in them. I think these are made for the younger teens & tweens (who weren't around the first time to enjoy them).
As for new fashions for the upcoming year that will look great on anybody, there are plenty to choose from. Wide boyish trousers, fuller skirts, fuller sleeved shirts, layered tops, and cable knit sweaters. It's almost as if there's two trends going on right now, skinny and volume, that contrast each other.
One thing not in style this year: doctors with bad attitudes!
I know you aren't looking to buy a lot of clothes but if you do end up getting a few pieces, there's lots of cute choices for you. Have fun!
