So when dealing with items such as the Spring Dress that have no stats on them (since I know HQ gives better stats than NQ), what is the difference between NQ and HQ? Is there some sort of aesthetic difference that I am not aware of, or is HQ on those items simply for the bragging rights of saying "I HQ'd that"?

Just it doesn't make sense to me currently, so hoping for some enlightenment. If it's just for bragging rights, why not just NQ the things so it's easier?
