Old Navy pajamas set (bonus bottoms) size 12

Old Navy Halloween pj set worn once cause I’m a sucker for my kids Halloween obsession over my own knowledge of things being to small for him so one true west for the top however I think the set pants were worn twice…I’m throwing in a bonus pair of bottoms just to add in…tag says 12 XL but nope I’d look at the measurements provided maybe a 12 but not an xl Old Navy Halloween Pajamas Extra pants Cool
