Topic: The Club House / BOP Clothing Allowance

I was wondering if there was anyone out there who could hlep me. I start with the BOP at the FMC Rochester in July. They sent me a packet of papers in which was a form for a clothing allowance. When I asked about this I was told to wait until I start. What I want to know is how much they give? What I can use it on? And most importantly, who has the best quality uniforms on the market, I ask this because I have heard conflicting stories. I appreciate any help with this.
