It does sound like "retail therapy" to me. Even if its not breaking the bank (you said spouse, so I assume all the monies are joint), it sounds like it's creating some serious stress . Is she working on developing her look, is she avoiding something, is she making up for lost time? Is it something else completely? I know a lot of people turn to retail therapy when something's wrong (we all get a dopamine hit when we obtain something we want). Might be worth talking about.
In terms of reclaiming the space, it is obnoxiously pop-trendy, but the "spark joy" method of getting rid of old things works for us in a nice, non-judgemental way. Does this thing still make you happy? Yes? Great, let's keep it and put it somewhere you can touch, wear, use it often. No? Thank it for the things it taught you (seems dumb, but it really helps), and send it on its way (return, resale, donation, trash, etc.)
