KIDS GET THE BEST COSTUMES

I get it.  I do.  Halloween is a kid holiday.  I'm not saying it is not also an adult holiday, but honestly it's a time where kids get to fully indulge in fantasy without any adults telling them that it is unhealthy and they need to focus on reality.
But darn it all, it's not fair that they get the best costumes!
Kids costumes really come in two basic varieties, only for kids and smaller versions of adult costumes.  In cases where the costume is a smaller version of an adult costume it can sometimes look awfully surreal due to the proportions.  Tiny zombies that have the same basic proportions as adult size zombies can be a bit silly.
On the other hand take a gander at these samples I've pulled up for ghosts.

This ghost costume, described as a phantom, is very good.  Basic black hands and face and shoes can be hidden in the dark for that ethereal floating look.  The light up eyes are a special treat.

The white color and gauzy strips are really the only thing that keeps this from looking like a Jawa (and yes, this same costume is sold in brown and giving a ridiculous name like desert alien phantom).  He's kind of like a Scooby Doo villain come to life.  That's a good thing, by the way.

The Phantom really deserves a close-up, because you must inspect the glory of the mask.  So simple and yet so effective.  In fact, except for the height, you wouldn't know it was a child.  Glowing eyes and a faceless black area.  Chilling and wonderful.  I'd give this kid two, maybe three extra pieces of candy.

YES!  Sheet Ghost!  Here's a commercial variation on the classic sheet ghost, complete with wavering ghostly mouth outline.  Just eyes or eyes with mouth, both are good.  It's so classic and cute and it conjures up just the right spirit for Halloween puns.

The above is a kid version of an adult costume of the same name.  It might require a bit of explanation.  Look closely and see the molded skull face under the hood.  That's good as it gives our ghost a frightening face but not immediately obvious at a distance.  It would seem like a Grim Reaper but that it is all white until you get to the bottom.  The black is meant to be not there, so you pair this with black shoes and what you see, in the dark (and conceptually) is the ghost "floating" in the air.  That's pretty clever.  Our next offering is in a similar style.

The inset picture is meant to demonstrate how this costume looks in the dark with the right lighting.  The child seems to be a full size ghost (hence the oversize head), not just a ghost of a hot dog or something.  The costume really comes to life in the dark with some black-light.  Which means that it might not be your best choice for trick or treat, now that I think about it.  Again, it's kind of cute.  Not sheet ghost cute, although this is admittedly based on the idea that the sheet ghost conveys, but fun.

I am jealous of both the quality and the price that allows kids to get away with paying less for a better costume while an adult pays 40 bucks for a tiny hat and plastic ax with a Walking Dead Official Merch sticker on it.  Ectoplasm all over that.

Keep your pumpkins black-lit.
