Welcome from Mid-Missouri. I'm 59 and started wearing kilts 10 months ago. It's really not that hard to wear a kilt in public. Everyone usually has some concerns about it at first, but the more you wear it the more confident you become. There is all kinds of support and knowledge available here. I think a UK is a good start, and as others have mentioned, you don't need all the accessories with a UK.
