Sold as set or individually • I have on Woolcano from Amazon kids merino base layer set size 11-12 (I am usually xxs petite), I prefer merino wool over cotton as it is more temperature regulating, less likely to overheat when you are indoors, and more odor resistant/sweat wicking. They make both adult and kids sizes. I've been getting kids and they are the perfect length on me! Comes in light colors and doesn't show through. My only complaint is the neckline on all the merino wool base tops I’ve found are high so I can only wear the with crewneck sweaters. Otherwise I wear the scoop neck heat tech uniqlo top linked in xxs • Amazon shearling boots 5.5, TTS so comfy and a great value Petite friendly winter layer, cold weather base layer, warm winter outfit ideas LTKgrwm LTKPetite LTKSeasonal
