"Fun fact: i hate clothes. Seriously, i hate shopping for them, i hate wearing them, i hate carrying them around."
So the ADT is the American Discovery Trail (I was going to look that up, too!), that IS a doozy. That's a lot of walking and if you plan on avoiding cities much of the time, then critical thinking about your clothing is a good idea, not a bad one. I don't know anything about the ADT other than what I just scanned, but I'm guessing a good bit of it involves either road-walking, sun, and humidity. Here's my take for your CLOTHING:
UNDERWEAR + SOCKS:
seems like a lot of women here (or other hiker blogs) prefer 2 pair that can be rotated daily (one dries on the back of the pack while you wear the other). You know your own body and preferences for hygiene, but "an ounce of prevention" as they say. I know you have the swim suit, but lined lycra isn't going to breathe as well as something like Patagonia briefs. For socks, maybe have 2 really-light pairs to rotate daily and 1 slightly-thicker wool for sleeping. That's a lot of time on your feet.
LOWER BODY CLOTHING:
1 pair of running shorts with no liner
1 synthetic hiking skirt (or hiking pants if you prefer. I like non-convertibles and a separate pair of shorts, but keep your convertibles if you like them. The skirt just seems like a smart solution for what I imagine the ADT is like).
1 Lightheart Gear sil-nylon rain wrap (to go over the skirt),
1 baselayer bottoms
1 rain shell (go cheaper like Sierra Designs Hurricanes or simple nylon dance pants. There's a thread here somewhere).
** Most of the above things can be layered.
UPPER BODY CLOTHING:
1 synthetic tank top (core base layer, in hot weather, in cities as needed),
1 button-down synthetic long-sleeve "sun" shirt,
1 L/S zip-top synthetic base layer (midlayer, light insulation),
1 100-wt or 200-wt fleece pullover (I like merino, too, but a fleece should be lighter, dry faster and quicker to clean. Look for something at TJMaxx, REI-outlet, Target, Lands End, etc.).
1 rain jacket
SHOES: find any trail runner/road running shoe that FITS you.
OTHER: swim suit, bandana, don't forget a hat, gloves, sunglasses
A GREAT PIECE GEAR TO SUPPLEMENT YOUR CLOTHES: a GoLite Sun Umbrella!
Here's what I think you should look like: look at "Ninja" in the 2d photo down:
Skirt, long-sleeve shirt for sun, sun hat.
Finally, don't worry about taking labels/logos off your clothing. Once a little worn-in and dirty, nobody is going to care if your jacket says "Patagonia" and also don't be worried about being, well, a little more serious in discussing your gear here at BPL or anywhere else. Please don't take this wrong, but your post sounds a little, well, cavalier about what seems like a major undertaking!
Good luck! Sounds like an adventure!
