Is it ok to put my bra in the washer and dryer?

I don't have that many bras because my bra size is a bit hard to find outside of Victoria's Secret, which means each one costs at least $50 for me. So each bra I have gets quite a bit of wear and they can stretch out. I was wondering if it is alright to put them in a dryer and washer because I put my Miraculous Bra in there this morning and it came out fine and fitting like the first day I bought it. I had thought my boobs had shrunk because the bra was stretched that badly but now it's perfect! I took the straps off before I dried it. I'm just asking if this is bad though for my bras because now I want to do this to all of them. I normally hand wash and hang dry but the results from the washer and dryer were very good!
