Angie, the 90s are my favorite fashion era (besides the one we're in) haha!
When I think of it, my essentials have scarcely changed ... just the cuts and details of them. Black turtlenecks, black brogue-style Docs, crew-neck sweaters and tees, a black slip-dress with a white t-shirt under ... and off course I went to Catholic school, so navy was still my color haha! I think I came of fashion-age in the 90s, which is probably why I love thinking back to those styles so much.
I also feel like style was democratized a lot ... the brand craze of the 80s died down a little and simpler styles and pieces meant anyone at any budget had a good change of being on-point style-wise if they wanted to be.
That's my reverie for the 90s done!
