I just wanted to add that I have harness dresses, harness vests, pull on harness, pull-on hoodie harness, and silk step-in harness. I use them for different things - so you may want to try a few. I'll use all the above for most of the year.. but when it gets really hot here, I'll use Chattiesmon's silk step in. My Mia has long hair and it's like she's not wearing anything. It's actually alot lighter weight than what her pictures show. And anything you need - you "can" find here on YT
Good Luck!
