Texture gives an outfit something to notice beyond colour. Maje UAE's Summer Textures edit invites you to begin there, then keep the surrounding shapes clear enough for the surface to make its point. A pair of trousers can provide a simple base for a more detailed upper piece, leaving the overlap between them easy to read.
A bag introduces another surface and scale, so consider whether it should echo the clothing or offer a quieter contrast. Let the individual garment descriptions tell you which materials and details are actually present. The summer mood comes from the arrangement you choose rather than a single required fabric.
