Continuity mistake: Charlie tells the psychiatrist that apart from being constipated everything is fine and the house is paid off. However later on when Walden moves in, it is said there are three mortgages on the house which Alan can't afford (which is why Walden moves in in the first place).
Chosen answer: Alan might have thought the bra was too fancy to belong to a regular woman, "I'd love to meet the girl who filled this", he says. He assumed it was one of Charlie's many women.
