I like my camo. Its warm, has lots of pockets (to carry rangefinder, binos, water and jerky for the long waits) and most importantly, unlike many other clothing, is very quiet even when moving. I also wear a camo stetson to keep the rain or snow from dribbling down my neck and also helps when the sun is directly against your eyes. The only non-camo part of me are my boots, which are dark green. When I am sitting for long hours, I like to carry a roll-up foamie. This is amazing for lying down in wait and falling asleep. Its not camo though, but I figure it can't be seen since I am on it. On cold windy days and wet ground, there's nothing like the roll-up foamie for lying on.
Buy good camo and wear it for every hunting trip. It can be cheap if you're not fussy. I got all mine used off craigslist. Even if you don't get anything, years from now, at least you can tell your grandkids when they look through the photos...oh and hear was grandaddy on one of his hunting trips. Wow...grandad, you used to go hunting?? Cool! Better than, but my dad wears jeans and a jersey to go to work too.
