uneven dyeing, any ideas?

This week, I dropped a shirt and skirt into a dyebath, and came out with an interesting problem. The purple looked more pink than I wanted, so I added turqoise... The back of the shirt and the sleeves started to change to more of a purple, while the front of the shirt and the skirt stayed pink. The color difference on the shirt followed exactly along the seams. I got both pieces from Dharma, and I am thinking... is it possible that the shirt is made of two different fabrics? It looked great while it was white, but it is amazing how dyes illuminate irregularities!

Are there any other reasons why certain parts took the turquoise, and why others stayed pink?

Obtaining different dye intensities on the different pieces of fabric that make up a garment is not uncommon for premade garments that are not PFD (prepared for dyeing). It's surprising for a garment that was sold for the purpose of dyeing to do it so obviously, though. Was it sold as being PFD? If so, it should be returned and replaced, if it has not been too long since the date of purchase.

The shirt was certainly made from two different lots of fabric. Different lots of fabric may take dye more or less well, depending on many different factors, such as the amount of spinning lubricant residue on the fiber, the age of the cotton used to make the fabric, the extent to which it was mercerized (if at all), and the presence of other impurities such as starch in the fiber.

It is the Big Scoop Cap Sleeve under their short sleeved women's shirts. It says "ready to dye." I would return it, but I made dyed it along with the skirt so they match. I pulled it out of the dyebath before the differences became too noticable. I just wish I could have gotten the whole outfit more purple rather than pink, but I've already worn it and everything, so I don't feel ethical returning it at that point. Next time, I'll do that!
