A practical question about personal colors

I have a hair appointment coming up and want to check whether Deep Summer or Deep Winter suits me before choosing a darker shade. I have been comparing dark clothes from my closet. Black gives a strong outline, yet a softened charcoal sometimes makes my features look less tired. That leaves me uncertain about the contrast I need. The descriptions of deep summer color palette give me useful terms, but I still need to test them against real fabric. I would make the comparisons without changing my makeup. I can gather fabrics with similar depth but different clarity. I plan to compare them in daylight with my hair pulled back, so the current hair color does not dominate every impression. Would you begin with muted plum against a brighter purple? I could note whether either fabric emphasizes shadows. I am especially curious whether the skin around my eyes looks smoother with one fabric, rather than simply noticing which color I like more. The result would guide the conversation with my stylist. If you have had to separate these two palettes, which comparison pairs revealed a difference you could see consistently? I would rather verify the pattern than trust one glance. I would appreciate examples using ordinary clothes rather than specialized draping kits.
