The Parshah of Tetzaveh deals greatly with how the kohanim (priests) and the kohen gadol (high priest) had to be dressed when entering the Mishkan (and in the case of the kohen gadol the inner sanctuary). In fact, the descriptions given in the Parshah are incredible precise and clear. One could actually (re)create the garments fairly accurate based upon the Torah descriptions. There is nothing vague in the instructions, I'd say.
As far as I understand (and I don't understand a single thing) the garments were to be worn exclusively in the Mishkan and possibly in the first and second temple, on Yom Kippur special requirements were to be met. What do our sages say regarding recreating the garments and wear them during communal service even though the third temple is still not around? Would it be disrespectful to dress in that particular way even though there no temple nor Mishkan arose in the present time?
