I'd rate the color on this mask as B+ and the form a solid C -- the beak is too fat for an insectivore like the European Robin. Robins have eyes on the sides of their heads so you'll be looking through small holes near the mouth when you go as Robin. This robin mask would pair nicely with an orange top and a grey or off-white pair of pants. You'll be trick-or-treating for insects.

Dress up as America's bird with this adult Bald Eagle mask. This is a pretty good likeness of the species -- B+ all-around. Wear with an all-brown outfit and put on a white waist apron backwards for your majestic tail and you're done! You'll be trick-or-treating for small mammals, fish, or roadkill.

If you'd like to go as a domestic bird, this chicken mask is a good choice. The depicted bird is a white rooster, so wear this with an all-white outfit. You'll be looking through the open mouth of this mask. You'll be trick-or-treating for grains and grubs. And you'll want to stay away from the Bald Eagle.

This owl mask is a bit hard to pin down to species. By plumage and facial structure it looks more like a Long-eared Owl than the more common Great Horned Owl. Since owls have front-facing eyes, you'll be looking out of small holes near the eyes for this one. A dirty brown or tan outfit would go well with this mask. A tan camo ensemble would also work. You'll probably be trick-or-treating for small mammals.

Dress up as a Mallard with this green duck face mask. I'd give the structure of this one a C, coloration is a solid B. There are small eyeholes at the sides of the duck's bill so you can see when you're swimming around on Halloween night. Pair this with a brown top, tan pants, and orange shoes. Bonus points if you have a white collar and blue chaps. If more than one of your buddies wants to be a duck, this mask also comes in domestic duckling yellow. You'll be trick-or-treating for duckweed and other aquatic vegetation with the occasional worm or snail.

Dress up as the most recognizable bird in the world when you sport this fun full face pigeon mask! This one looks great and makes such an easy costume -- plumage variance in this bird means you can pair the mask with virtually any outfit for a plausible look. If you'd like a cleaner look or have more friends who want to go as a flying rat, this pigeon mask also comes in an all-white version. You'll be trick-or-treating for French fries, popcorn, pizza scraps and whatever crumbs you come across.

This mask is a pretty good likeness of a Scarlet Macaw. These big loud birds have amazing rainbow plumage so you can have fun with the clothes you wear with this one. On top you could wear a red shirt with a big yellow belt or a yellow shirt with a red bolero. On the bottom you could wear blue or green shorts over red tights. You'll be trick-or-treating for fruits, nuts, and seeds.

Why are Northern Cardinals depicted with yellow beaks in popular culture and novelty masks? Chicks have brownish grey beaks that become red when the bird reaches maturity. It's never yellow. On this mask I'd like to see the black around the beak a bit darker. Otherwise this is certainly recognizable as a Northern Cardinal, one of the most common neighborhood birds found in the eastern United States. This is an easy costume -- just wear red. You'll be trick-or-treating for sunflower and safflower seeds.

This mask of an Emperor Penguin is spot-on as far as plumage and structure go. A+. You'll be able to look out of the bird's open mouth. Wear this with a white outfit topped with a black jacket (a traditional tuxedo would also do nicely) to complete the look. You'll be trick-or-treating for squid and fish.

You'll be the saddest one in your group of bird friends -- you're dead! The flightless Dodo is an icon of extinction. Wear this Dodo mask with a greyish outfit and yellow shoes. You'll be trick-or-treating for fruits and nuts, probably -- accounts are murky.

Tip: Wear a pair of alien style novelty sunglasses like these along with this funny costume t-shirt for some added humor. 

You'll be warm while cosplaying the strong female superhero character. This is a fitted style zip-up hoodie with all of the patriotic stylings that make Wonder Woman recognizable. The red bodice is framed by blue sleeves with white stars. The zip costume hoodie also has handy pockets, a sparkly W logo at the chest, and yellow cuffs that replicate the arm cuffs typically worn by the comic book character.

Note the size of these is made as "one size fits most"; for further guidance, shoppers have shared their sizing experiences in the reviews.

One of Gus's most notable features is his deer-like antlers and ears. A headband like this one that combines both features is easy to wear and a must-have first piece to your Gus Sweet Tooth costume. The headband costume piece is made to fit most kids and adults.

Gus's look includes a red plaid flannel shirt. This top in men's sizing is available in a variety of different plaid color schemes if you're looking for an alternative costume style.

Gus wears a pair of heavily patched, worn and distressed jeans as part of his look. You might already have a pair of jeans in your closet to complete your outfit, or you can get a pair like these distressed kid's jeans.

Here's another solid colored simple Regency-style empire-waist dress that would make a great start to a Bridgerton-inspired costume. This is a highly rated dress that Bridgerton fans love!

This dress in girl's sizing is marketed as a Hamilton-inspired, or Colonial-style look, but the high bodice empire waist with sash belt can work as a Regency-era outfit as well, though you might want to add tissue or other material to puff up those sleeves. This dress style also comes in white.

This dark and dramatic long sleeve costume dress in the Regency style is especially perfect if you're looking for a warmer gown outfit for Halloween or a Bridgerton-style event.

Light brown would work for Eloise; dark brown and black are also options to best match a variety of natural hair colors.

While this wig is marketed as a Marion Antoinette style hairpiece, the voluminous up-swept white hairdo would work well for a Bridgerton / Regency style costume. Use this magnificent white wig for your Queen Charlotte costume.
