Vestments: it's one of those changes where nothing will change. Basically lots of Evangelical clergy don't like vestments and don't agree with them and have been not wearing them for, well, ages. This change means they're no longer breaking canon law.
I went to a church where nobody wore robes for ages. That was my local church when I became a Christian. It went with a lot of other things - the Eucharist wasn't important, there was a completely open table (i.e. Anybody could receive), we didn't really notice the Church seasons, there was quite a bit about penal substitution in the songs and preaching.
When I started training I got moved to a church much higher up the candle - everybody robed, including servers and verger, much more Eucharistic, more seasonal, different theological emphasis. It took me about a week to know that this was where I was at home in church-ology.
The no robes thing has a lot going for it, if you like that kind of thing. But for me vestments are important. When I put on my alb (white robes), stole (scarf) and chasuble (big cloak in hing that goes over the top) I feel that I have put on Christ and that I don't represent myself, but something that is much greater than me. It doesn't feel 'look at me and my gorgeous clothes', rather it feels that my individuality is absorbed into the robes that I wear and the place I stand behind the altar. It's me but not just me: it's an aspect of the mystery that's at the heart of the Eucharist.
And I also like worship to be beautiful and vestments to me are part of that. We give back to God the best that we are capable of. But that doesn't work for everyone and I do get that for some people vestments feel like 'look at the clergy and how important they are!'.
