It looks like something I wouldn't wear anywhere that has mud or rain.1

I am not a fan of maxi dresses when they're made of a t-shirt/jersey material, as they tend to warp the body. Maxi skirts, though, I think can look nice, but it depends on how they are worn. If they're too stiff and boxy, or paired with the wrong top and accessories, you may end up being reminiscent of the Duggars.
The picture you posted looks good, and the color compliments the individual.0
