Congratz once again on your weight loss. You are awesome!
I didn't lose nearly as much as you, but I understand. Most of my clothes I can still work with and I'm very thankful for that. But it still stings when I look in the mirror and see the jeans that used to be very flattering are now saggy. I have bought a few new pairs, but none that looked as good as my old ones.
I think if I had to replace most of my clothes I would cry. It's like getting blindsided with a break-up. You spend so much time thinking about all the great things that will happen in the future, you don't notice the good things you have now slipping away. It would be different if you chose to get rid of it on your own, but when it's collateral damage like that it sucks.
