Is $500 budget good amount to invest in clothes for only one time shopping once or every two years?

I am not cheap I am frugal which is two different now. I have lost a lot of weight after working out for one year I went from size 22 to size 10 and I feel incredibly comfortable with myself. I clothes no longer fit me all baggy. Now I have a budget but I only shop once every two years or so. I only wear black bottoms so that way it's easier. Do you think $500 dollars for a one time clothing shopping is enough or is it way to much. I'm going to consignment stores I don't shop at expensive luxury store none of that. The only reason I plan on going store shopping my clothes no longer fit me properly. After this investment I will not be buying clothes.
