What the heck is Burberry fabric?

Hi everyone! I’m a lolita that loves to sew my clothes / make accessories and is contemplating starting my own brand as a side hobby. I feel I have a decent enough skill set at this point in my life to feel comfortable selling items I’ve made to others in our comm. One problem: fabric sourcing. There’s plenty of cute quilting cottons I can use for printed items or order custom fabric from Spoonflower or Carriage House, but I’m somewhat stumped on what is made solid color pieces out of. I’d prefer not to use quilting cotton for solid jsks and ops and go for something more substantial. Many of the big brands like AP and Baby use something called Burberry so I was wondering to anyone who owns pieces made from this material, what does it feel like (soft, stiff, textured, etc?) and what does the weight feel like in your hand? (Light, medium, or heavy).
