It is true to size and comfortable. I normally wear an XXL. According to the sizing guide, I was between an XL and an XXL. I got the XXL and it fits me PERFECTLY! Flattering, but still flowy.
I really love the dress and have already received a lot of compliments. The material is a little thin and wrinkles easily. But it isn’t see-through and it is a perfect summer dress! The material itself isn’t super stretchy, but the sleeves have good elastic so it is comfy on my arms. Love it!
