We rarely need an excuse to buy a new dress, but in this case, we have a good one. Every time something starts trending on Amazon, we listen and it's worth it. Right now this Milumia Button Up Maxi Dress [1] ($16-$36) is selling like crazy, and we can see why.

The comfortable maxi dress is the perfect transitional piece that you can wear every season. Its versatile silhouette makes it easy to pair with sandals in the Summer or sneakers and booties in Fall. The button-up front and smocked waistline make it a superflattering piece that's great for all body types. It even comes in a wide range of sizes. Its best feature, though: it comes in over 44 different solid colours and pretty designs. From floral prints to deep maroon shades, we want them all.

Like most popular items, sizes are already selling out fast. Do yourself a favour and get one (or five!) to complete your wardrobe now.
