Tie-dye...it never really gets old does it?  Tie-dye was all over the runways for Spring 2016 and while it always channels a somewhat bohemian vibe, this year's crop doesn't push you into deadhead territory.  Tie-dye sweaters however are usually printed to look like tie-dye rather than using a true twisting and knotting technique.  Even though you've probably seen 1000's of printed sweaters it's often a tricky endeavor unless your factory really knows what's its doing.  (And I can tell you from personal experience, they rarely do.) 
The last image is a printed sweater made to look like traditional Japanese Shibori which I worked on with Thakoon for his Spring 2008 Collection.  8 years old and it still looks great!
Barney's has a pretty extensive offering of Raquel Allegra's tie-dye tops, tees, dresses, and pants.  If you like the Thakoon sweater above I recommend this great sweater paired with cropped denim multi-wash jeans.
