Sundresses are simple and
sexy dresses with
spaghetti straps. Some sundresses resemble
nighties, in the regard that they expose the whole arm, some to much upper chest, and back, except that the material with which sundresses are made is about a
whopping 2% more
substantial.
Males seem to appreciate sundresses on females as some suggest, "Why don't you wear a sundress?", by default, when females appear undecided on what to wear. Perhaps this is because sundress is one letter away from undress.
