Functional Yes it does serves the purpose of keeping u warm. I wore it for straight 4hrs and it was warm and comfortable.
Fashion Its not thick, so it does not give a bulky look. Its crown [its top part] is not too long so it wont droop and not too short to fit like a shower cap . The colour is the same as in d display. Quality is good
The fabric is good, stitching is impressive, it keeps you warm. Though it comes in FREE size but if you have a big it might be a bit uncomfortable (personal opinion). Well, flipkart delivery was good
