It reminded me also of a liturgical dress. It was made here in mobile (Priscilla's fabrics) it was on the tag. Really all what I did was cut off the sleeves, take the dress a bit in on the top side, and serge the bottom to take up the hem.
Here is the end product!
Kind of has a retro feel to it but I really like it! I added a belt to finish up dress. And its no longer the green monster. It is just green :)
