My husband and I have been loyal customers of Cycology for the last five years buying more than 10 items from you. The last long-sleeve Frida shirt he bought for me was too tight but the previous Frida shirt in the same size fit perfectly. It was discovered that the material used was different (spandex was added to the later shirt, making it compressed and very form-fitting.) I wrote customer service (Deb) about my problem. She could not understand why the shirt was tight. I think everyone knows spandex is used to tighten up or compress garments. She told me if I had all the original packaging and tags and I had not worn the shirt, I would receive a refund. If not, "sorry". I had worn the shirt, that is how I discovered it was too tight! My husband would not have ordered the shirt if he would have known that the material and sizing was different, making the shirt much tighter. Lesson Learned!
