Back in the 2015 winter event's Winter Event, there are two options to obtain the costume. One would be acquiring them through winter lockboxes which enemies drops only for the duration of the event. The other option would be to directly purchase them from the Seamstress for 400 gems each as they are also available there for the duration of the event. The event is now over, so they are no longer available.
