High-quality, durable linen dresses

I've purchased a few made-to-order linen dresses from Ukrainian and Lithuanian sellers on Etsy the past few years, as they ship to Norway (and are VOEC-registered), and Cottagecore styles are pretty easy to find there. I have small kids, however, and their snotty noses and sticky fingers mean that my clothes get a lot of wear and tear through daily life and frequent washes. All my dresses have developed thin patches and small holes. I try to repair what I can, but I'm wondering if the quality of the linen might be a factor here as well.

Any recommendations on online shops or Etsy sellers with high quality and durable linen clothes? Must ship to Norway.
