By way of a vague answer to Justin's question about my last post (though please do leave comments with more specific answers/other thoughts too), I was just reading this from Meredith Kline in 'Images of the Spirit'.
In the broad parallelism that we have traced between the Genesis and Exodus creation episodes, Aaron's priestly investiture corresponds to the original creation of man in the image of God's Glory. The priestly vestments had the Glory-cloud for a pattern. This becomes readily apparent once we have recognized that the tabernacles too was a replica of the Glory-cloud, for there are striking similarities between the tabernacle and the priestly-vestments.

The tabernacle... serves as an intermediate link in a remarkable symbolic series: the tabernacle is a replica of the Glory-Spirit and Aaron's vestments are a replica of the tabernacle - and thus also of the Glory-Spirit.
That Aaron's garments were designed to be a likeness of the earthly tabernacle and of the heavenly Glory-tabernacle is evidenced by their materials, form, function, general purpose, and the ritual connected with them.
