It's a no. Always.
"Who says you can only wear open-toed sandals when it's warm?" -Above^
We do. While many women think that there is nothing wrong with wearing tights with open-toed shoes, we view it as one of the worst fashion offenses one can commit. But then again, you see lots of women walking around these days with visible panty-lines and bra straps showing. There used to be a time when people were concerned about good taste. They avoided fashion faux pas and tried to adhere to certain standards so that they would not look ridiculous or out of place. Unfortunately, that day has long passed. We now live in a world where it is deemed perfectly acceptable to wear white after Labor Day, vertical and horizontal stripes in the same outfit, and tights with open-toed shoes. Not only is this TACKY, but it defies the whole point of open toed shoes. However, when wearing those type of shoes you want to show of you'll be showing your feet so make sure you have a pedicure and toes that won't scare any one.
ps: we love these Rebecca Taylor Swarovski tights
