I don’t really like referring to them as cheap, but more frugal. I like thrifting and have found numerous good dresses for an even better price. Sales and the like are always something I keep an eye out for and more of the more luxurious dresses are ones I will never wear out anyways.
I have occasionally splurged on dresses or shoes to get something high quality, but only when I know the return system is good. Women’s clothing have the dreadful curse of never being the size they say they are.
