Tea Party Dress and Play Suit

Hi! I have made the Tea Party Dress twice-- each time it came out great. Attaching photos below. I really appreciate your notes in the pattern and the amount of detail you provide. I am now making Option D, the Tea Party Play Suit. The pattern doesn't list snap tape in the list of notions needed, so I wasn't sure what kind to get. I purchased some (the only kind my fabric store stocks) in which the snaps are 1.5 inches apart. Apparently that is not the right kind, as three snaps won't fit. I am guessing that 1.0 inches apart is what you intended? Thx for your response, and hopefully you can add this information to the pattern.
