stretchy, skintight, preferably natural fiber, long-sleeved women's "base layer"?
I have a set of Smartwool long johns from 2010, that was when I started biking a lot. I wash them with the rest of the laundry and hang them to dry. I find the long sleeve tops to be pretty warm though, I'm not sure I'd wear them under a sweater indoors.

Merino wool base layers - which are the most durable?
I have some Smartwool baselayers (the version that is now called “Classic” going on 25 years. The newest ones are 5-6 years. I prefer icebreaker for its fit and shape retention for things like snowboarding or anything more active. Smartwool tends to bag out on me especially since I’m not washing it much because of wool’s great natural anti odor. Once I wash and throw it in the dryer, it gets back to the original size and shape. I don’t have this shape retention problem with Icebreaker no matter how long I wear it for before washing but I usually line dry Icebreaker. My Icebreakers are about 6-7 years old, the newest one being 3. I have not had any durability issues with it but I’m using the Oasis 200 line.

How do synthetic base layers compare to merino wool base layers?
I know everyone is bragging about wool. I prefer my Sitka and stone glacier heavyweight synthetics over my 250gms smart wool base layer sets. Stationary while fishing I'm much warmer in the higher end synthetics. Theory is the wool is too damn breathable for stationary cold.

I find good deals on Smartwool base layers on Sierra .com. Just picked up their classic base layer bottoms for $40.
