BUT you definitely need a chemise, (I bought this one from H&M in the size XL, beige, and it fits great) because the dress is kinda see-through especially under the sun 
The fabric is veeeery pleasant to touch, very airy and follows the body's movement. I really like its quality. The color is amazing, fresh, summerish and sunny! I love how it fits me, I like the elastic-band waist, I believe it looks nice on my waist. I would ADORE it even more if there weren't any pockets on the upper part for this specific event. It's ideal though for a casual outfit, I love it.
