This is a Hayley Paige Occasions dress in their "crinkle chiffon" fabric. It is not a heavy weighted fabric and definitely is accommodating if you are wearing it in the warmer months but still has a little weight to it. I wore this for a wedding in early July when it was sweltering and was comfortable with it!
I had the dress immediately dry cleaned and it is in perfect condition.
Added tidbit: I am very heavy chested, I wear a 32DDD/ 32G so this dress was a bit snug in there (so don't be mislead by the pictures, other girls who had the same size dress in the party but a smaller chest where comfortable but mine was a little snug cause of the girls :)
