Oh no ... that's some bad news to hear. That certain clothes aren't being accepted despite you making them exactly as the example. My programmer re-wrote the entire code for that section to fix it, but I guess the bug remains :(
How many times did this happen to you? Do you know if it was on a certain category or not? For example, was it dresses?
And if you find any typos, please take a screenshot, that would most definitely help me out!
