At 45 degrees, the porch is colder than you planned for. Walking to the door is fine. Sitting still for two hours, from about 6 to 8 p.m., is different, because the cold comes through a thin jacket once you stop moving.
Most people fix it with a costume over a sweater. Here's a quieter answer: a hoodie you'll still be wearing in March. Below are seven things to check, in the order they matter. The last one is about money, and it names the price worry plainly.
7 Things to Know About Wearing a Hoodie Through Halloween Week
1. Fabric weight: look for 8 ounces or more
Fabric weight is listed in ounces per square yard or grams per square meter (gsm). Most tees run 4 to 6 ounces. Around 8 ounces, about 270 gsm, is midweight, and it's where a hoodie starts to block wind instead of letting it through. Hold the fabric up to a window. If you can see light through the weave, it's a layer, not a coat.
2. A hood that holds its shape
Pull the hood up in front of a mirror. A single-layer hood slumps onto your shoulders and leaves your ears out in the wind. A double-layer hood stands up on its own and stays put when you turn your head to say hello to a three-foot ghost. If it only works when you cinch the drawstring, it's not holding its shape.
3. Cuffs and pocket depth
Push the sleeves to your elbows. Ribbed cuffs should stay there. Then slide a hand into the front pocket. It should go in to the wrist, with room left for a phone. You'll spend two hours reaching into a candy bowl, and warm hands between visitors matter more than you'd think.
4. The porch
Sit on a chair or a step with a cushion, because cold climbs up from concrete. Pick a hem long enough to cover your lower back when you lean forward to the bowl. Pull the hood up when the wind picks up and push it back when a kid walks up, so they can see your face. A costume over the hoodie is fine, but the hoodie is doing the work.
5. The pumpkin patch
A field at 10 a.m. in late October is colder than town, and by 2 p.m. in the sun you're warm again. Wear a tee underneath so you can pull the hoodie off and tie it around your waist. A darker color hides hay and the mud from the last wagon ride, and cuffs wash clean.
6. The bonfire
Check the tag before you stand near a fire. A cotton-heavy blend handles a stray ember better than synthetic fleece, which can melt where a spark lands. Expect it to smell like smoke the next morning. Wash it cold and hang it to dry, and the smell is gone by lunch.
7. The cost-per-wear sum
A good hoodie costs more than a tee, and hesitating over that is fair. So do the sum with your own numbers. Say the hoodie costs $49. Count the cold days where you live from mid-October to mid-March, which is about 150. If you wear it one day in six, that's 25 wears, or $1.96 each. Ten wears is $4.90 each. Forty wears is $1.23 each. A costume you wear once costs its whole price for a single night. If you want more on treating yourself this way, we wrote about a good Halloween gift for yourself that outlasts October.

Who gets one
A hoodie suits the person who's always the one outside: on the porch, at the sideline, at the grill while everyone else goes in. If you're shopping for a dad, a husband or a brother, a men's lion hoodie reads as calm rather than loud. If you'd rather give words, an inspirational hoodie with one short line is easy to wear to the hardware store and the pumpkin patch alike.
For the gift side, we laid out the thinking in skip the skulls and give something worn in November. And if you're weighing a hoodie against other options, a tee, a candle or candy for a calm friend sets them side by side.
If you want one for the porch this week, the Stay Brave lion hoodie is a reasonable place to start looking.
