Chef WorksBib Apron

How long are the ties? I only have use of one hand and need to tie from the front.

Is it waterproof? I searched waterproof aprons and it was about the top of the list, but looking at the specs I don't see it listed as a feature??

I am 5"4 and have 30" waist, will this be too large for me?

looking to buy 10 can you consolidate shipping so im not spending 10 dollars on the product and 50 on the shipping?
