Choose your buttons for for free when you purchase an item that already has a buttoned option. On the Petiole Dress, Seedling Top, and Sprout Top, this happens automatically. For the Gardening Dress, enter code FREEBUTTONS on the check out page.
Select your buttons for your garment. The five on the left are shell and the 10 on the right are wood. They're all around a half inch in diameter. Since both are of a natural material they will have variations between individual buttons.
The most uniform shell option is the White Shell.
The most uniform wood options are the Curved Black, Bowled Black, or Curved White.
