I’m between a 3 and 4 so I guess like 3.75 lol. White is definitely white and not an off white. You can see the comparison with my ivory bed. It had a strong chemical smell upon removing from the package. It was packaged in a plastic zipper thing as most bedding sets are. I opted to hand wash/soak it in the bath tub for several hours with “free and clear” detergent. It did remove the smell. I did dry it in the dryer. Took a while and decided let it finish air drying. There was a very small amount of lint in the dryer which I was pleased to see. Some reviews stated they had a lot of “shedding” with theirs. I have not had that experience at all. It is ok in terms of softness. Could be softer but it is still comfortable to sleep with. I would say it’s a medium weight. I haven’t experienced any sweating due to the comforter. So far I am overall pleased with this purchase.
