Hi Piyo,
Usually i wear a coat on the outside, inside i still wear a sweather or a fleece pull over, beneath still got thermal wear and stocking cause in some place, the winter can be -5 to -10 degree. A coat or a fleece jacket is not sufficient.
Hi Chimes, i do think they have more than 1 pc. Btw, the seller got a quite a bit of plus size coat for winter, u all can check it out.
