It happens with our fashion sense, our cooking skills, our finances — you name it. We all think back to our first independent experiences and wish we could do things a little differently. Same goes for our very first apartments (what were we thinking, trying to paint those walls ourselves?!). That's why we've gathered some decorating advice we wish we had known when we first moved in . . . because even as editors, it takes a couple of times to get things right. The best part is you can apply these tips today, no matter if you're at your second or 16th apartment, in a studio or a four-bedroom spot. Did we miss anything? Let us know in the comments!
