They all look nice but the materials are all synthetic, this cardigan for example is 100% acrylic. Run & Fly also sells some similar knitwear but also acrylic. I had one of their jumpers and it bobbled horribly.
If you like fun prints in bright colours but prefer good quality cotton then I recommend Scandi brands like Duns and Maxomorra.
Obviously I know many people won't mind the synthetic fibres and the Popsy stuff seems to have a huge following on FB so you might be fine with it anyway. 🙂
