For the necklace, Model Magic would be a good idea. It's easy to form and you would poke holes in it to string it all together with durable beading wire. The boots would have to be boot covers to get that exact look, and you would want to use the same material for the gloves to match. The bandage socks are probably the easiest - for costumes that require this, I use the self-adhesive bandages you can find at Walmart - they look great and they won't stick to your skin and be a pain to remove. The dagger and sheath could be attempted in any number of ways, since it's a small prop.
