I like the garments with something different and fun around neck.
For this design, I pick the scarf looking around neck.
I use lace pattern with sock weight yarn for around neck to make soft looking. Then I use DK weight yarn for Body part to make good knitted fabric.
Also the garments can be worn two ways. with the waves up ( Lace collar wide up as photo above), with the Ripples up (Lace Collar side down).
It is fun design. simple shape, but a lot of stitch pattern in the design.
This design is available at Ravelry or Etsy, or your LYS.
