I'm one of the sweatiest people I've ever met. I've slowly gotten better at layering and how to use clothes for different situations, but I agree it's a big factor and there's some unwinnable combinations.
For instance, I've finally learned to embrace "long-john" style long underwear under my pants, but it's only possible because I'm working from home. They are amazing layers for warmth, but unlike additional shirts, hoodies, jackets, scarves, hats, long underwear can't be casually removed. You have to take off your shoes and your pants! So if (when) I was going into an office, I always made the choice to have cold legs during the commute but comfortable legs all day. Now I can wear them in the morning, take them off if the day warms up, and put them back on whenever the temp. drops again.
But overall I'll echo a few comments in here that some of the more expensive gear, even as base layers, really is better technology. And getting to know my body and my situational habits, it's been possible to figure out layering clothing that worked for me, but only because I was working in tech and felt like I had enough money to get it wrong a couple times... If I were still living on a student or even "average" budget, I would've been much shyer about trying some new $30 shirt just to see if it agreed with me.
sorry, late reply: REI sells a totally ok pair, i'm not even wearing silk ones. The trick for me is that in this era of remote work, I'm not required to be in places heated to the warmer end of room-temperature. And I can pretty casually take them off if/when the day warms up.
You simply need layers and good enough deodorant. A bit of experience helps as well - you learn how warm to keep your base layer after some time. If you sweat in non-standard places (like under breasts), spray deodorant might be your friend.
I personally deal with this because of hormones - I'm a female in my mid-40s, so I get to have hot flashes and night sweats during part of my cycle right now.
