Where can I find soft and warm oversized cardigans for chilly days?

I visited a clothing store to buy a cardigan two days ago. I wanted something soft and warm. I also wanted something oversized and comfortable. But when I checked the cardigans I felt disappointed. Some were not soft enough. Some felt too thin. Some did not look comfortable. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some cardigans looked better but options were limited. Some were warm but not stylish. Some looked perfect at first but fabric was not good. I remembered a cardigan I wore before that looked nice but did not feel cozy later. That made me hesitate even more.

To check more variety and options while scrolling many online marketplaces including alibaba I found many cardigans. Some looked soft and warm. Some had better designs. Some showed good comfort and style. There were many options available. This made me excited but also confused again.

Now I am thinking should I trust online options for warmth or go with local stores for better feel? What would you do in my place?
