We've used a light-weight but just the right thickness denim one-piece perfect for this time of year. It's a basic A-line one-piece with a stand-up collar, but the key features are the front opening with decorative loops and Pocket on both hips. Pocket in particular are so large that they wrap around the back a little, making them very convenient as they can hold a lot of things. We've also given it a special wash to create a distressed look. It's woven with a blend of slub yarns, giving it a vintage-inspired vertically faded texture.
