Disguise Spartan Halo Costume

We ordered the Spartan Locke Classic Muscle Halo Microsoft Costume, Small/4-6 Black. My son is 48 lbs and about 48" tall and the Small fits perfectly over light shorts and a t-shirt. It would be nice if the opening in the back went further down to allow for a wider opening but as long as we're careful while putting it on it works. As with other similar costumes, it's made from thin but somewhat stretchy material so there's some give and should last through Halloween. And, like with other similar costumes I don't expect this to survive through multiple washes, or through multiple wears with lots of active pretend play. (Just setting expectations for those new to buying ready made costumes as I was with my first son a few years ago.) The mask feels sturdy and he's able to see well enough through the mirrored eye holes. Peripheral vision is limited though, but that's how it is with all the costume masks. In the end, my son loves it and is excited for Halloween.
