An Aerobics Instructor

It’s as simple as putting the pants under the pastel-colored onesie you already own. And you can make the leg warmers by cutting off the feet on a pair of kid-sized socks. 80s genius.

Get the look: Primary babysuit ($8); Primary baby legging ($12); Gymboree socks ($7); Suddora headband ($3)

Harry Potter

The scarf is the key item in this magic (vs. muggle) inspired look, dreamed up by Leah and Jenni over at Love & Lion. Peep your local Good Will store or comb through your closet to find one—anything in a burgundy(ish) hue will do—then throw on a white tee, casual black hoodie and oversized glasses. The true marker of Harry Potter is that penciled on forehead lightning bolt, after all.

Get the look: Cat & Black hoodie ($8); Fruit of the Loom t-shirt ($8 for 5); GrinderPUNCH Kids wizard glasses ($9); Elope scarf ($25)

Eleven

Yep, the Stranger Things character is still totally on trend. All you really need is a pink dress, blue cardi and knee socks. Oh, and a box of Eggo Waffles.  

Get the look: Primary dress ($20); Primary cardigan($16); Rocky tube socks ($16)

Bubble Bath

Dress your kid all in white and affix white (or transparent) balloons to his clothes. Done and done.

Get the look: Primary legging ($14); H&M t-shirt ($5); mikimini showercap ($10)

Arthur

Yep, the aardvark—and star—of the PBS Kids TV show is also one of the easier Halloween costumes to pull off. All you need is a denim bottom, mustard-colored top, oversized glasses and paper ears, according to blogger Arin Solange.

Get the look: Old Navy shirt ($10); The Children’s Place skirt ($13); FancyG glasses ($2)

Belle

To pull off this Beauty and the Beast ensemble, just pair a sleeveless yellow dress with white above-the-elbow gloves. Oh, and the ultimate prop to finish the look: a rose.

Get the look: Primary dress ($15); Party City gloves ($9)
