Re: Turquoise suite
I think that black embroidery on a turquoise suit would be too overwhelming. You can have embroidery in a lighter blue shade and silver embroidery will look really nice as well.
For the baby pink......gold embroider will look fine as long as it's not over done. You can have embroider around the collar/gala and some on the edges of sleeves and a little bit on the edges of the kurta. Keep the embroidery light and don't use dark gold embroidery. Use a pale gold thread.
