Hello! I made a pair of Loose Pants from the Comfort menu, using a zipper closure, and saved the file. Today I went to make another pair, and because I wanted to make this pair with an elastic closure, I opened the pattern from scratch, and selected lingerie elastic from the Closure menu. But to my surprise, the measurements of the pattern pieces were exactly the same as on the pattern closing with a zipper. Can that be right? Thank you! Janet
