10 breezy summer dresses that are perfect for every dress code—and under $40 at Prime Day

• Amazon Prime Day 2025 offers a variety of summer dresses under $40.
• The sale includes floral dresses, maxi dresses, and dresses with pockets.
• Prime Day 2025 runs from July 8th to July 11th.

No matter the dress code or weather, dresses are always my unofficial uniform for summer. They're lightweight and breathable (perfect for warmer temperatures), can make me look pulled together in an instant (perfect for those extra-lazy summer days) and designed to work for a variety of occasions, no matter if I'm attending a formal summer wedding or just grabbing brunch with my girlfriends.

Some of my favorite summer dresses are styles that I discovered on Amazon, and at Prime Day 2025, many of the retailer's top-sellers are on sale for under $40—but only for a limited time. With Amazon's Prime Day sale winding down today, July 11, the retailer is offering last-chance deals on hundreds of cute summer dresses, with styles ranging from floral dresses to maxi dresses and even dresses with pockets that are equal parts functional and chic.

Ahead, shop 10 cute summer dresses I'm eyeing at Prime Day:
