Party Boutiques Guide
A baby's first Halloween is mostly for the parents and the photos. The baby doesn't care — but the grandparents absolutely do, and the photos will surface every Halloween for the rest of that child's life. Baby costumes need to prioritise two things above all: softness against skin and ease of dressing. Any costume that involves hard edges, tight elastics, or complicated layers is a recipe for a crying baby and a frustrated parent.
The best infant costumes are essentially wearable soft toys: plush all-in-ones, hooded bunting bags, or lightweight onesie-style outfits with an animal or character motif. These can go over a regular baby onesie or sleeper for warmth and are typically quick to put on for a photo, which is realistically all the wearing they'll get.
Find baby and infant costumes at Party Boutiques, 7724 Yonge St in Thornhill. We carry a selection of infant sizes from newborn through 18–24 months, and our team can help you find something that's safe, adorable, and stress-free to actually use.
Anything touching a baby's skin should be soft and non-irritating. Avoid scratchy trims, stiff headbands, or anything with small decorative parts.
A plush bunting bag-style costume is the most practical option for newborns — it goes over any outfit, provides warmth, and photographs beautifully.
If the costume will go over a onesie, order one size up from your baby's actual age size. Trying to squeeze a diaper-padded baby into a fitted costume is frustrating for everyone.
