A lot of great insight and suggestions already but I'll add my own two cents.
First, I am 6', 200 pounds, and average build...
Socks? I love my Darn Tough crew socks and Injinji toe sock liners, paired with my Merrell Moab 2 vent shoes (I prefer the heavier-duty shoes over trail runners but not the bulkiness of boots)
My primary hiking shirt is my Outdoor Research Echo sun hoody. In warmer weather, that's all I wear (for my shirt anyway). On cooler days, it then serves as my base layer with a fleece or shell on top.
For pants, if it's hot I am wearing my Trailhead shorts from Coalatree and, if it's cool enough for pants or where ticks are a huge threat, I wear my Trailhead pants (as you can surmise, I like the Coalatree stuff).
Other clothing I carry:
- REI Ranier jacket
- a puffer jacket (late Fall through early Spring for day hikes, all year if backpacking)
- REI fleece beanie
- a pair of glove liners (again, late Fall through early Spring if I'm just day hiking)
