Knit with 100% alpaca fiber that is not dyed! The colors are the natural colors of the animals sharing their fiber. Because these are not dyed the black is not a typical dyed black and may appear as a dark brown in some lighting. Also, the white is almost ivory in color since it is not bleached. The ribbed knitting of this dress gently hugs your body, yet allows full range of movement. The alpaca is soft and warm, and this cute, tank dress is perfect for climates that vary from morning to midday to evening. It is easy to layer with and stay comfortable. Works well with the knit sleeves/ shrug or a shawl. If you would like it be knit in organic merino wool please contact me, this is an option as well. Please note that this is made completely of animal fiber and may itch people in sensitive areas, I find that cotton clothing worn under the alpaca helps with this and you can still receive the health benefits of wearing animal fiber. Each item is lovingly, handmade by myself once your order is placed. Hand wash only when absolutely needed. Please visit woollywhotknots.com for other made to order items and ready to ship inventory.
