Until you get some good sinky experience, I suggest that you go light on the clothing. Fabric can gain a lot of weight in a mudpit. Also, bare feet are the best if you can do it, both for the feel of the mud between your toes and for extraction, but if you are worried about anything under the mud cutting your feet up, I generally use "aquasocks" and I tie those suckers on tight with extra laces.
Neoprene socks are also good if you can find them, because they're very tight and they protect your feet but they never get stuck...but I often can't find them.
Don't do the crocs. They'll slip right off your feet and you'll never find them in the mud.
Also try to stay away from any shoes that are inflexible and/or heavy, and yes, boots are very bad. They can really get you stuck. Someday you may want exactly that. But you don't want it on your first time.
After you get a few sinkings under your belt and you have a good relationship with your mudpit, you may wear anything you like. And you may be pleasantly surprised at how well some items (especially synthetics in dark colors) can wash out
That means that it is possible to develop a wardrobe that's re-useable!
But I'd like the fate of your sinkwear to be a pleasant surprise instead of an unpleasant sock, so on the side of caution I will advise you not to necessarily expect any sinkwear to survive an outing.
So acquire it for as little money as you can possibly spend.

You also run the risk of losing your shoes, especially if your wearing a loose fitting shoe like croc's.
