Our company uniform is black shoes, black pants, black belt, standard white shirt with tie and shoulder boards (stripes). There is no company jacket or hat. During summer you can only wear a hat while sitting in the cockpit (and that's so you can use one for sun protection). During winter the rules are thrown out the window if you need something to stay warm. If the only jacket you have that's warm enough for a given mission is bright pink, you can wear it... although I'd try to avoid getting in that spot!

Some captains wear some fairly colorful winter jackets or hats. There's more than one captain with a sealskin hat, one of them is a spotted one so it looks like he's wearing a dalmation...
For winter I'm using black Danner boots with 600 grams of thinsulate, black flannel lined carhardts and thermals under them with a carhardt jacket over my shirt (and occasionally a sweater under the jacket, but I only started adding that, periodically, since new year's). Since I bought my winter gear after I got up here, I bought black clothing. Last summer I used black Catterpillar steel toe boots with black Dickies work pants and started out taking my leather flight jacket on flights... that lasted for a few weeks and then I gave up on trying to avoid getting Jet A on it fueling airplanes and started wearing the carhardt jacket, once I bought it. The jacket is midweight as well as everything else (excepting the boots). I bought a set of midweight bib overalls and have a set of heavy thermals as well but never wore either one, even at -40 there was no need for them. I have a black hat that covers my ears and apparently makes me look like some kid named mikey from some movie as well as some black gloves. I also do keep a thick black military issue balaclava (face mask, goes all the way down my neck) in my bag and will use it in addition to or in liue of the hat if we go somewhere windy and it's cold enough. I bought goggles too, but have only used them once or twice.
We actually don't officially have wings either, but one of the captains gets small batches made up at a time and I bought a set that I wear.
The part 135 guys' dress code is a little bit more lax and if you're on the freighter you can wear whatever civilian clothing you want. During winter some guys from all the areas cheat and just wear a sweater and don't wear the shirt under it since no one can tell if it's there or not.
I reckon that's probobly more detail than you had in mind, but there you go.
