Comfy Yet Non Frumpy Dresses

I’m a new mom and looking for cute comfy dresses to wear around the house but could still look cute out and about. I feel like everything I find is really frumpy and has no shape. I’m proud that I’m pretty close to back to my pre pregnancy shape and want to show that off but still be comfortable and functional. I feel like whenever I search for cotton midi or maxi dresses they all look like tents or little house on the prairie vibes. Want to avoid stuff like the attached or at least would like versions that are little bit more flattering. I don’t want bodycon but some waist definition would be nice. Any recommendations or links to dresses that you’ve loved? I want natural fibers - at least 90% and maybe some options for warmer and colder months.
