If your product range is going to include sizes ... lets say ladies
shoes for example, then you will need to provide a list of all possible
sizes you will be using or think that you might be going to use to
cover the whole range of shoes on the Online Shop.
And what countries size you are using, for example US sizing or Australian
Sizes as sizes vary from country to country.
It is common practice to include in the Online Shop a Size List page
for the buyer to compare.
So you might have a range listed from Womens US Size 4 through to
US size 16.
Same with childrens sizes, Boys Sizes, Girls Sizes, and Mens Sizes
It is the same with clothing i.e. mens shirt sizes .... small, med,
large, X-Large, XX-Large, XXX-Large.
"We" need to cover all of our bases.
