You've heard of red hot, but now it's time to really crank things up with these white-hot dresses! What's better in the summer or spring than donning that warm weather dress that really makes them sweat? We've gathered the best of the best white dresses from this season, so you can grab a snapshot of the latest trends and really knock them dead.

The first frock we're checking out is the definition of a showstopper. Perfect for a summer birthday dress, night out on the town, or cocktail party, Milly's 'Trapunto White Dress' is absolutely stunning. This twill dress features hip-height slash pockets, offsetting the boning and darts at the bodice. Its formfitting top suits a slender upper half and flairs out in a structured way from the quilted waistband, giving off a classic feminine shape with baby doll hints. Its simple shape certainly gives off subtly sexy hints with its exposed back and seriously sweet exposed gold back closure. Its 98% cotton, 2% lyrca fabric mixture not only keeps this dress smooth, but comfortable, as well. For those of you on the hunt for a seriously sexy little white dress, this is definitely it. I will warn, though, that it'll run you about'cringe'$300. But not to worry, if you love the shape but don't want to pay the price, you can find shorter, form-fitting strapless options from Xhileration and Gap.

Let's change things up. A serious one-eighty from our seriously sexy Milly dress, we've got the perfect summer picnic dress from an unlikely place: Patagonia. This 'Women's Netty Dress' showcases a clean-cut classic V-neck in organic cotton seersucker material/lightweight polyester. This unique fabric blend makes this option ultra breathable, while retaining a feminine feel. Its under-bust yoke and adjustable back tie showcase the dress' natural A-line silhouette with ease that's subtly perfect for casual summer afternoons. Its thirty-six inch length falls to above the knee, and poly-cotton blend make for a soft and easily translatable summer sundress. Ringing in at $85, it's currently running for just under $50, so snag one of these puppies up fast!

Another great option for a white sundress with a completely different feel is American Eagle's 'Ruffle Dress.' This sweet, 60s-inspired option falls a couple inches above the knee, and showcases a sweet neckline ruffle, skinny tie cinching you in at the waist, and thin, adjustable straps. Its easy one hundred percent cotton fabric and metallic stitching detail keep this white dress extra light and airy. Plus, its fully lined interior will keep you covered and fret-free when it comes to its soft and comfortable feel. And, with a full-retail price tag of just $44.50, and sale-price of $29.95, you really can't ask for much more from this flirty, functional summer white dress!

So, whether you're on the hunt for a seriously sexy white hot party dress, picnic-prepared Patagonia eco-friendly blend, or super sweet, 60s-inspired white frock, you'll definitely be keeping things cool as the weather heats up.
