Style is one of those things you can trust will probably change over time. I always say that your style shouldn't be just one thing since you aren't just one thing, however, your style shouldn't stagnate either (that's gross). But that's not to say the things you used to love have to disappear forever. It's a fun practice to look back at the styles we used to wear, not only to have a giggle, but to get re-inspired too.
As a child of the 80's (and the even more challenging early 90's), there aren't a lot of trends I'd want to revisit, but sometimes we can resurrect certain themes in new ways. When we bring back elements from our past, we are allowing our histories to be seen. We can share different sides of ourselves, recycling the past with fresh eyes, to create a style that's more fully our own.
