As a women, when will you wear a 5.5inch high heel? May be you will answer me either to a private function, wedding or some special party. Majority of women's interest when attending a party or private function will go shop around the dress, make up, hair-do and many more.
Anyway, a 5.5 inch high heel can be wear casually like her, Victoria Beckham. Classy?? You define yourself.
