Q: I performed a bath. Then made whudu. I made whudu without clothes on. Is my whudu valid. Do i repeat the prayer? (text)

A: Modesty is part of faith. It is best to not prance around naked. Musa (AS) used to bath with clothing on. Try to wrap a towel, sarong, etc. for greater self respect.

Whudu is valid.

Prayer performed later (with clothes on) would be valid.

Allah Certainly Knows Best.
