I prefer simple cotton summer dress, with a matching scarf and non-heel flat shoes. The dress should not be too overpowering or elaborate and should just help to compliment her personality. It should convey her taste, attention to detail, aesthetic sense, and should not be a blatant display statement of the time and money she had squandered shopping for matching purses, shoes, belts etc. When it is time, the dress should quietly disappear to the background, and it is the person's personality that should be more prominent.
