Hi! Whoa! Long time, no see! Did you use a dry iron, or a wet one? If you previously used dry, try wet. Especially if the fabric is a little thick or particularly wrinkled. Or you could spritz the dress with a squirt bottle and go over it with a dry iron. Before you do the whole thing, though, test the heat & water someplace on the dress where any problems would be less noticeable. In fact, you might even want to turn the dress inside out to do most or all of the ironing.
