With something as simple as a plain, casual racerback maxi dress, I don't believe it's always worth it to overspend. I loved this maxi dress (and its price of ten dollars at F21 - see what I mean?!) so much that I got two in black and the darkest shade of army green. They are so easy to throw on, unbelievably comfortable, and always look casually elegant. The great thing about plain maxi's is that you can add so much to them, mixing both high and low pieces: jewelry, a leather jacket, a blazer, a belt, a scarf, anything really. With the black, I put on a vintage skinny belt, Alexander McQueen silk skull scarf, Hermes spiral ring and bracelet, Free People knuckle ring, and Chan Luu wrap bracelet. On the green, just a multi-chain layered necklace from Intermix. This is one of my favorite necklaces because it can be put at any length (I usually just wrap it once like above) and goes with absolutely everything due to the mixed metals.
