You know that feeling when you spot the perfect Zara spring dress that has airy materials, a flattering silhouette and expensive-looking details - and then you flip the price tag over and immediately put it back.

Luckily, Amazon is full of trend-forward dresses that deliver the same elevated aesthetic for far less.
