Do I have to pay for an item before I click for the size?

[abcast15]

I am trying to purchase an item, but I can't find where I click for the size.  I don't want to pay and not get the correct size.

This is how I do it,I would contact the seller and ask for an invoice indicating the size ,and the total cost.

You can't ask for an invoice before purchase.

Contact the seller and ask how to specify the size.
