Those players who pay attention not only to the "battlefield capabilities" of their characters, but also to their looks, will be happy to hear that there's an option to modify the wardrobe of the main hero / heroine. Mass Effect Andromeda allows the player to do so, but the place where it can be done is hidden quite well from the player and the game itself won't inform you about it in any way.
In order to change the look of your character, head to the lower deck of the Tempest. You can get there by traveling north from the central part of the ship (where you can find the research and Strike Team terminals) and jump down, or simply use a ladder to get to the lower floor. Afterwards, you have to head north until you reach the room of the main character.
Inside you will find numerous places that can be interacted with, but you are looking for the Wardrobe located to the left of the room entrance - the exact location can be seen on the above screenshot. Interact with the terminal and you will be presented with the outfit selection screen, in which you will be able to choose from one of the three "casual" outfits for your character - used when, for instance, you are on the Tempest. There's also a second tab where you can choose the colors of your combat armor.
