I attempt to shop Catherine's using Safari on my smartphone. The site hangs, freezes, then reloads. I use Safari on my smartphone and do not have this issue with any other site except for Catherine's and Lane Bryant. Despite numerous complaints from me, they haven't corrected this horrible issue. And, on the rare occasion I am able to click on an item, you have to click on an item, then use a drop down box to see if it's available in your size. That's stupid. Why not have the sizes in tiles as well as the colors? That way you can click on either a size or a color and see if it's available without wasting time.
Most of the time I just give up and use Avenue instead. The quality isn't as good but their site actually works and it's laid out in a user-friendly format.
