If you are going to another country to buy fabric and the purpose is to get enough for a dress, there are diferent amounts you may need to buy, depending on the kind of dress. For a dress, you may need to measure the length of the dress you want. Measure from the person's shoulders to the bottom of the dress, double it, and add several yards, depending on the syle of dress, the size of the person who will be wearing it, and the width of the fabric. The amount you need also depends on if the fabric has a nap, border, or a one-way print. You could need as little as 3 years to as much as 10 yards. There are many variables.
