Buying Guide

Comfort and Fit

Kids need to move freely while trick-or-treating. The Morph alien costume slips over clothes with a secure fit and adjustable cuffs, while the WISHTEN set includes a soft elastic waistband and adjustable suspenders. For toddler sizes, see our best toddler boy Halloween costumes for more options.

Durability and Ease of Wear

Costumes should survive a night of running and climbing. The inflatable alien uses a battery fan that lasts up to four hours and inflates in one minute. The WISHTEN set is made of polyester and plastic with sturdy metal clips. Both are hand wash only but hold up well.

Fun Factor and Design

The Morph alien creates a hilarious carried-away-by-aliens effect that draws laughter. The WISHTEN set offers a unique steampunk look with goggles, beanie, tutu skirt, suspenders, and gloves. For more creative ideas, browse our best halloween costumes for girls.
