Can make of dress become new

In ordinary is much attention to dress up of I.I have a yellow 95% tencel 5% spandex maggie sottero blaire wedding dress that I recently wore to a wedding. My friend that I went with spilled a blue drink all over the front of the dress. I've been reading online that you can hand wash tencel but I cannot find how to maybe get a stain out. I would get it dry cleaned but every time I've taken a garment with a stain to the dry cleaners, it has come back with a hole where the stain used to be. Therefore, dry cleaners are out of the question. So, can someone please help me make my gorgeous sottero midgley asm3184 wedding dress look like new?Because I really hope it will become the new, I like this Mori Lee 35043 wedding dress is not like discarded.
