What to do with clothing intended for ones lost

I was very thoughtfully given two little baby vests when I was expecting twin boys in 2020. They died at 20 weeks, so never got to wear them. I kept the vests along with some other items in their memory box. I had a rainbow daughter in 2021 and never put her in the vests, as I couldn’t bear it at the time. I’m wondering what other parents have done about items gifted for babies that didn’t make it? I am pregnant again and wondering if it would be nice to honour the boys by letting the vests be worn, or whether they are better honoured by keeping those vests for them, as they will never have any other items of clothing of their own?
