I know with most colors making sure the fabric comes from the same dye-lot is the only way to guarantee bridesmaid dresses will be the same color.
Is it as important if your bridesmaid dresses are black?
One of my bridesmaids was recently in a wedding and wore a black dress very close to the style I envisioned for my girls. Assuming everyone is on board with that style, and we can order the same dresses for the my maid of honour - I think it would be great to be able to save someone some money! However, I won't be too happy if the color is different...there are only the two standing with me so I think it would really stand out if they were even slightly different.
Should we just get new dresses? Or is black, black as long as the type of fabric is the same?
