Confusion

I used to like what I wore…then I had kids and everything is always dirty so I never really pay much attention to it and don’t fit into it very well anymore. I need to do a massive clothes cull because I have stuff from 15 years ago still hanging around that I can’t face throwing out and lots of pre-baby things that I still like but can’t see myself fitting into again…I think my style has changed but I’m not sure what it is now so I don’t know what to buy, and because baby T is still so little there is no point in getting new clothes (apart from pjs…which I’m totally doing very soon) til my body shape changes again…advice anyone?
