Designer Casual White Maxi Dress (Where to Enquire)? - white maxi dress

My good friend has been looking for a long white dress (cotton clothing or preference) as a designer of high-end, but as a wedding dress. Ideally, you would have an empire waist and shoulder straps. She wants to make this very casual beach wedding. I thought about the level of Prada and other designers in order.

Any suggestion that the designer can ask you something? Are there any designers who do not think that it is worth seeing.
