Looking for a dress to get you through the dog days of August? The Gypsy 05 cotton maxi dress is the answer.

You’ve probably seen these bright, casual gowns on Hayden Panettiere, Lauren Conrad, and Christina Aguilera recently — they’re a chic way to keep cool and comfortable in the summer heat.

Gypsy 05 sibling designers Osi and Dotan Shoham make these dresses in a solar-powered factory in Hollywood using organic cotton and rich vegetable dyes.

We’re interested in knowing whether the designers’ celebrity fan base stocked up on the frocks because of the company’s ethics or because they’re insanely flattering. But we’re converts: M.J. has two (in lipstick red and cantaloupe) and is eyeing a third.

They come in a range of bold colors and ombré patterns. Demand has been so high that many e-tailers are backordered for weeks, so get your pre-orders in now.
