in Edition Clear Qur'an by Talal Itani / Al-Ahzaab (The Clans)

33:51You may defer any of them you wish, and receive any of them you wish. Should you desire any of those you had deferred, there is no blame on you. This is more proper, so that they will be comforted, and not be grieved, and be content with what you have given each one of them. God knows what is within your hearts. God is Omniscient and Clement.

33:59O Prophet! Tell your wives, and your daughters, and the women of the believers, to lengthen their garments. That is more proper, so they will be recognized and not harassed. God is Forgiving and Merciful.
