An unwritten fashion rule says we should all invest in a little black dress, forgetting that the same goes for the white dress!
It doesn't have to be short, it just matters to be part of the wardrobe!
In summer, nothing looks more beautiful than a white dress with puffed sleeves. It can be long, short, loose, tight, linen or minimalist. You will look beautiful anyway and above all you will feel comfortable.
Try to make sure that the one you buy is as low as possible and pay attention to the material. If it fits well on the body it can have any shape and no other single detail.
