They don't have a choice because of how the character models and gear interact. If the outfit has tights that can be seen on the foot, that HAS to be part of the foot gear model. Leg gear ends at the ankles and can't affect the feet.
It would be nice if they reused they model to make a plain version though.
Likewise, I'd love a version of the waistcoat (for my alt) that could be dyed completely, instead of having to make it jet black if I don't want the two-colour effect.
