After this I looked and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and in front of the Lamb. They were wearing white robes and were holding palm branches in their hands. Revelation 7:9
The only type of heavenly clothing described in the Bible is a robe. The robe could be an actual type of clothing or a metaphor for the “robe” of righteousness that covers us thanks to the death of Jesus for our sins. Unity of clothing is not a requirement in heaven. As long as our clothing is not sinful, why couldn’t we wear what we wanted? I would prefer jeans. What about you?
