Aeromax Jr. Astronaut Suit with NASA patches and diaper snaps

Are the patches removable?

Does the 6-12 month size come with hat?

My son wears 18-24 month clothing. Halloween is still a month away and I am questioning which size to order. Anyone suggest a size?

Does the 6-12 month old size have footies (covered feet)? Description seems to say yes but 2 reviews from last year state otherwise.
