I purchased this wally bag and the 66" bag to transport the clothing for our destination wedding in Europe.  I used this bag for my wedding gown and the other one for everything else.  I had a HUGE princess style gown with a long train and several layers of petticoats...even with all that fabric, it fit perfectly in this bag, and I had no problems carrying it on the plane.  The first flight was on a large plane and the second flight was a TINY plane where they put it into the steward's cabinet  The bag is very well made, and my gown needed minimal pressing upon arrival.  I would recommend using an extra long plastic garment cover (from a dry cleaner) before putting it in this bag...just in case.  Highly recommended.
