I spotted a good coat in a charity shop that fits my shoulders and has plenty of life left in it, but I cannot decide if the muted green is a useful color for me. The changing room has harsh overhead lights. I cannot trust my usual mirror check there. Outside, the coat seems softer and less yellow, which makes the decision even harder. I am keeping my clothing budget small and would rather leave a bargain behind than own a coat I never reach for. I have looked through while thinking about this, though I am wary of treating one photo or one label as a final answer. Would you compare it with a scarf you already wear and check the combination outside before deciding? I could hold it beside the shoes I wear most to see whether it fits into real outfits rather than an imagined wardrobe. I am interested in methods that work on the spot without asking a friend to judge every purchase. What signs tell you that a color is worth taking home despite imperfect lighting? I do not mind walking away from it but I want to learn a better process for the next good find.
