Many companies make seriously warm gear, eg, suitable for AK. Don't go overboard or you'll have the opposite issue. Suggest layering, I routinely ski in single digit or negative temps wearing spandex longies, down sweater (go for count 800 or above so it'll be thin), insulated Gore Tex pants and breathable shell. If you really want to be subtropical underneath, add an insulated jacket; I like Primaloft insulation + Gore Tex. IME being cold starts with hands and feet. Get insulated gloves with Gore Tex liners; wet gloves get cold fast. I use Marmot Guide gloves, several other good brands like Black Diamond. Not a fan of Hestra for serious cold but others like them. Hand warmers inside are old trick that works. For boots, suggest Intuition liners. They will improve the handling of most boots and are surprisingly warmer than factory liners. Alternatively, get Boot Gloves. Finally, make sure you start warm. Weird number of folks tramp around outside wearing half their normal gear, go into the lodge not realizing they've lost several degrees core temp, then throw on gear and take off to ski. Fail. Have a coffee first. And keep your hands warm the whole time; don't go bare handed when you carry gear around. Good luck.
