When it comes to warm-weather style, Jessica Alba always seems to get it right - and her latest sundress look is the perfect example. Floaty, feminine and easy to throw on, it's the ultimate spring and summer dress to whip out for special occasions and everyday outings alike. Alba's exact sundress is from Zimmermann, which retails for about $1,325 - ouch. Thankfully, the Prettygarden Boho Maxi Dress delivers a similar breezy silhouette and easy elegance - all for just $35.
