There's only one thing we think about when we see sunshine on a warm day: spring dresses, linen pants, and flowy tops. Sure, style is always a huge factor, but comfort is the top priority while working from home or running errands. So while loungewear or pajamas have been our go-tos during quarantine, spring is here, and it's finally time to replace your sweats with sundresses that are lightweight, breathable, and oh-so-stylish. 

Our list includes trendy styles like maxi dresses, wrap dresses, and slip dresses. And the best part? These sundresses are all under $40 on Amazon, so you can buy more than one!

Best Maxi: PrettyGarden Halter Neck Long Maxi Dress

Buy It: Starting at $16; amazon.com

Maxi dresses and loungewear sometimes get roped into the same category, but this style from PrettyGarden is an upscale version of the trend that’s just begging to be worn outside. The breathable cotton dress is super versatile for multiple occasions; depending on your accessories, you can wear it to a socially-distanced lunch or wedding. The nice tie-back design gives a unique choker-like appearance, and it ties around the waist for a flattering fit. While we love florals for spring, we also love polka dots.

Spring has sprung with this mini that’s a quintessential spring dress thanks to its bright, sunny color and petite florals.

The tunic has a three-tier design that adds an exciting dimension to the dress. And over 2,000 shoppers love the loose fit and long sleeves that are stylish, but won’t make you feel hot. However, if you’re into the baby-doll look, the dress is available with ruffle sleeves as well.
