I have found seersucker quite resilient and wrinkles considerably less than a pure linen. A cotton/linen or cotton/linen/silk blend will also be a little more to your taste than a pure linen regarding wrinkles IMO. Mine wrinkle way less than a lighter weight pure linen. Another thing to consider with pure linen is the weight and type/design of the fabric (which it seems you have as you mentioned "lightweight"). I have a pure linen jacket that is a bit thicker and almost tweed like in its appearance and it hardly wrinkles at all vs. my lighter weight herringbone pure linen suit that wrinkles just by looking at it, lol. I have learned to embrace and enjoy the character of it and I think in time you will find yourself in a similar situation. I try and limit my trips to the dry cleaner to as little as possible because it breaks down and slowly shortens the life of your garment (especially summer jackets as many are partially fused construction). I will iron at home as needed but will only take my jackets and trousers to the dry cleaner when they really truly need it as a last resort.

As I recall there have been a few threads in the past that discuss how frequent, or lack of frequency, people are taking clothes to be dry cleaned. Best of luck in your search and I hope I helped a little.
