My footwear was the most expensive I've shelled out.
I have some Bald Mountian moccasins that come up and just above my ankle. At the time they originally cost $550.00. But since I was working the faire at the time I got a discount of $450.00. Of course that was at a time I had money.
A friend of mine who moved to Hawaii a few years back, gave me her knee high Bald Mountian moccasins that normally sell for $800.00.
I sure did luck out on that.
The Bald Mountian shoes are custome made to your foot, as are many other footwear offerings nowadays at faires. They are not cheap, but they fit, and they are comfortable.
I've picked up some really cool shoes at K-Mart of all places for about $14.00 that work well too. Depending on what outfit I'm wearing will determine what shoes I wear.
As for weapons, my first and only weapon for years was a small eating knife. As time has gone on, I have quite an arsenal now. More knives than ever (a few I've actually found), a sword, gun (not real), and a few other goodies. Ya, like I'm going to wear all of that stuff at one time.....good way to really make my back hurt!
As for tankards, hit your nearest Thrift store. There's bound to be plenty of them of all kinds. Hey the ones with the Playboy bunny on them are cute. You might even find one with your real name engraved on it.
Geesh I have lots....I use them to fill up my treasure chest for display when needed. I found some really cool wooden goblets at a Thrift store too. I had to tell people to stop giving me mugs, I have an over-flow of them.
As for garb, most I've made myself.
