I know this is one of the great unanswerable questions as it can very by crew on the day, but does anyone have experience taking a wedding dress as carry-on on Qatar?

We will be flying business class, SYD-DOH-FCO first leg on the A380 and second leg on the 787. Neither destination should inspire a lot of people to carry heavy coats in September, but I would be keen to know the size of coat closets on both aircraft - I know new aircraft, even widebodies, tend to have smaller coat closets than the 747s of old.

If closet space is at a premium, what are the dimensions of the overhead lockers; would it be better for a couple to pick seats behind rather than beside each other to maximise the length of their overhead space?

Grateful for any advice.
