They always manage to make the overalls look like felt stacked on top of the generic red shirt... so the straps are very thin... but too wide for the shoulders. The hats are surprisingly accurate. Of course the mustaches are always butchered. I'm not sure why they don't know what the bros' 'staches look like.... and if the messed up 'stache is there... where are the sideburns? Gotta have the right sideburns if you do the mustache.
Also, the gloves don't matter much because you knoooow if they included gloves, they'd just be like Mickey Mouse gloves. Or, according to the "Halloween Costume Producer's Law," if you produce one thing surprisingly accurately (like the hat), then something else must suffer (probably the gloves) so they thought: "Ah crap, they're gonna look horrible according to the law.... let's just not include them."
