Trying on this ultra light down puffer coat from Uniqlo in size XS which has room to layer. Note: I'm also wearing a light long puffer vest underneath which I also linked. I would need size XXS in the coat if I didn't want to layer underneath since XS is looser on me. Update 11/18/24: I bought this coat in size XS but even with a vest underneath I can still feel the chill when it's 50 degrees and under. I prefer my Amazon long puffer jacket by the Orolay brand for the best warmth for New England. Also linked. Kids ultra warm heattech leggings in size 11-12. Women's version also linked. For size reference I'm 5' 2.5" and 115 pounds. LTKSeasonal LTKOver40
