What would keep me warm all the way home?

To stay warm on your way home, consider dressing in layers, starting with a moisture-wicking base layer, followed by an insulating layer like fleece, and finishing with a windproof and waterproof outer layer. Accessories such as a warm hat, gloves, and a scarf can also help retain heat. If you're using public transport, a hot beverage can provide additional warmth. Finally, moving briskly can generate body heat and help keep you comfortable.
