"If petite shoes fit buy them in every color."
It doesn't matter that you wear petite (small) size shoes or big sizes, any shoes are not an easy item of apparel to find in your exact size. Now are you finding it hard to search for your shoes in petite size?
So here is what I think about shoes being petite. Although the word petite interprets as "small" or "tiny", fashion industry refers to it as "short".
So women are classified as petite if they are 5'4" and under. Nowadays, there are more and more clothes manufacturers that cater for special size petite women.
Now what you refer to as petite size shoes is actually small shoes in my understanding. And most women who are petite proportionally have small feet. So that's why petite women look for petite size shoes.
Now where do you find your shoes if you have small feet. It depends how small your feet are. There are a number of stores that specialize in small size shoes. You can find the list of these stores that carry smallest shoe sizes just here. They are really hard to find in averge petite clothing stores.
However if your shoe size is 4 or bigger then you should feel lucky, as there are many stores with fabulous "Cinderella Shoes".
Remember if you do "find the shoe that fits buy it in every color". ;)
Here is the small shoes size guide for general reference. However,
please do check each manufacturers size guide for the accurate sizes, as
they may differ.
