Both of the shirts from Zara that I bought required that I wash them before I wore them, as instructed on the care labels. Unfortunately, after being washed, the size of the products decreased. I took the t-shirts back to Zara, and while I was there, an employee questioned me about how to properly care for the garments. In my original post, I mentioned that when I washed it, I only used the cold water setting and didn't use the 30-degree spin option. On the other hand, the sales associate stressed that customers should avoid washing or dry cleaning these tops. What a ridiculous concept; in what other way are soiled items supposed to be cleaned? Immediately, there is to be a switch in the shirts that are being worn.
