For anyone interested, two programmes on UK television seem to promise raincoats, or at least trenchcoats.
On ITV1 every night this week at 9.00 pm Dervla Kirwin in Injustice - promo pics show her in a black trenchcoat.
Channel 4 at 9.00pm on Thursday, Sarah Beeny is shown in a long trenchcoat in a promo picture for her new series on houses falling down.
No guarantees, but they might be wworth a look!
