Olive Clothing UK cotton check plaid midi dress pockets one size please read

This dress is from Olive in the UK. They list it as cotton flannel, but the feeling of the fabric is more like the gauze baby blankets are made from, or like cheesecloth that’s soft and warm. Simple pull-over style midi dress with pockets; one size, with bust around 19” across and total length around 42”. This dress is cute and cozy, but the quality of the sewing is terrible. After two wears and a trip through the wash, you can see it started coming apart at the seams, pictured; they refused to replace, refund, discount or anything. I tried some basic mending but you can see it’s still coming apart. I would recommend either taking it to a pro for repair or taking it apart at the seams to resew it, something I’m not willing to do. Price reflects that! You could also upcycle it. Smoke-free home with pets.
