Fashion trends tend to repeat themselves. What's in fashion now is probably going to fashionable again down the road, whether fifteen, thirty, or fifty years from now. I think this is one reason bargain-hunters like me get so addicted to thrift store shopping. If it was popular ten-plus years ago, chances are you can find it in a thrift store.
Right now, popular fashion strikes me as a whole mess of later 20th century revivals. We've got some Mod style from the 60s, maxi dresses and sky-high platforms from the 70s, skinny jeans and high waisted shorts from the 80s, and flannel shirts and floral prints from the 90s.
I'm also seeing a lot of clutch purses.
The clutch purse first appeared as a fashion item in the 1920s and 1930s, but the ones I've been seeing in all the trendy shops like H&M seem very 1980s.
To me that means bold colors, boxy shapes, and fun textures. A few minutes of searching the purse rack at the thrift store and I found two!
