Knit with 100%alpaca fiber. The colors are not dyed, they are the natural colors of the animals sustainably sharing them with you. The black is not a jet black, and appears dark brown in some lighting. The white is also not bleached, and is close to ivory in color. This dress is super stretchy. It gently hugs your body, while allowing full freedom of movement. Warm and cozy this dress will keep you! You may choose the main color of the dress from the drop down menu. If you want the stripes in a certain order, please let me know in a note at purchase. If you don't leave a note, I will choose the color of the stripes and the order, keeping the gradation of color as the focus. The sizes are general sizes, and since this dress is stretchy, the sizes are forgiving. You may choose one of the general sizes, or you may send measurements of your body. The measurements needed are: Bust Waist Hips Shoulder width (across back) Length of arm (tip of shoulder to wrist where you want the sleeve to end) The dress is approximately 33" / 84cm in length. Note...The more the fabric is stretched outward, it will shrink in length. Each item is lovingly, handmade by myself once your order is placed, made just for you : ) The dress is made with animal fiber, which can irritate sensitive people in sensitive areas. Wearing cotton underneath helps. Please visit woollywhotknots.com for other made to order items and ready to ship inventory.
