It also needs to be loose fitting enough that it does not cause my dress shirt to get wrinkled and have at least one front pocket where I can put my phone and keys.
I don't ride if it is raining or bitterly cold, so those things aren't an issue. Price is also not an issue.
This looks promising to me but it looks like it may not be warm enough on very cold days:

Hard parameters there, but you also don't indicate (1) a riding style or (2) total distance biked. You a hard pusher or are you just letting life take you on its journey? Is this a 2 mile commute or a 6 mile one? Those two things are going to impact how you dress in general and what you'll run into. A headwind with a 2 mile commute can be done with little sweat, but if you have to push into that for 6 miles you're going to be breathing good
I think you just need to buy what works for biking and carry a dress shirt with a cloth to wet & wipe down with and towel to dry off with in a backpack.
On a 45-50 day I suggest a t-shirt & some softshell jacket. At 20 you won't be wearing that softshell at all and probably be focusing on some windproof shell with a few (literally two) layers of wool underneath.
My suggestion is you expand your mind for multiple options. That softshell won't (likely won't) keep you dry if it rains, and a windproof/waterproof shell at 45 will make you sweat, so it'll likely be different clothing depending on conditions, unless you're a fair weather biker.
