"Casual" covers a lot of ground — a mini for a hot day and a long-sleeve maxi for a cool one are both casual, just for different situations. Here's what's actually under $40 right now.
Quick answer
Six real dresses run $34–$40.01: the Floral Ruffle Mini Dress ($34), V-Neck Long-Sleeve Dress ($36.17), the Vintage Oil Painting Print Dress ($37.10), the Spring Summer Notch Lapel Shirt Dress ($38.01), the New Casual Beach Travel Dress ($38.01), and the Zip-Front A-Line Maxi Dress ($40.00).
For hot weather
The Floral Ruffle Mini Dress is the shortest, coolest option in this price range — sleeveless with a straight mini silhouette.
For cooler days
The V-Neck Long-Sleeve Dress covers more skin without sacrificing the casual, easy fit that makes a dress simpler than separates.
For an easy, low-effort look
The Spring Summer Notch Lapel Shirt Dress leans toward a shirt-dress silhouette — a relaxed, lazy-day style that still looks put-together.
For a longer, more covered silhouette
The Zip-Front A-Line Maxi Dress goes full-length while staying in this price range, useful if a mini or knee-length cut isn't what you're after.
