I've been hunting in earth tone bib coveralls and a olive colored fleece Gortex jacket forever. Lots of pockets is a plus.
I buy my bibs large enough for a heavy sweater or synthetic liner underneath if necessary. The wildlife really doesn't care how you look.
Camo is kind of over rated IMO. What game sees most is motion, chances are if you don't move they won't see you or hear you.
A few trips and you will make your own wish list, I wish I had this or that with me. Don't forget your ammo.
Old worn and many times washed materials make less noise than new clothes do.
I have a pair of Cabelas (on special) soft cotton coveralls, a size to large, that works well as another layer if needed.
I (now) always have something else with me to put on if the weather changes. Even if it just a rain poncho and/or a blanket.
I came real close to being in serious trouble when I was caught in a freak pre dawn summer storm, the temperature dropped 40 F in an hour. I wasn't dressed for it and had no backup. Sideways freezing rain, sleet and a 30 MPH wind can cause you real grief quick.
Good comfortable, water resistant or water proof boots are a must.
