The good: correct fabrics for the price, finishes first saw acceptable given the price. The bad: the liner as previously mentioned is the lowest form of so needless back easily seen since the buttocks through the dress. The M is actually an S, but even with the right size I doubt the chest arrives. I added a tissue to close the neckline but even so it remains tight. And I'll also change the lining for a less transparent and more long tissue.
I recommend taking at least one size bigger. This dress is more suitable for small to see very small chest because the cervix happens well below the chest. And it is worn with leggings or without lining the beach.
