I had to go to Downtown Vancouver yesterday, to volunteer for something. I decided to drop by Sears [where I worked], and The Bay.
It seems that The Bay sells Silks Waistless Tights [style #19295P] again. I asked about it, and the lady said that they sell it only in winter. Once it gets to spring and summer, they do not stock it anymore. I do not think she is completely right, but she is probably close enough.
Therefore, if you live near The Bay, then I encourage you to check it out, so that you could save on shipping.
Thank you for reading!
