Treat denim as something to play with, not an outfit already decided. Maje Kuwait's Denim Studio invites a closer look at the relationship between the upper and lower halves. A jacket changes that outline immediately, especially when its hem falls at a different point from the layer beneath.
A top can introduce another mood without asking you to replace the denim base.
Compare the arrangement as a whole, leaving one element familiar while another changes. The interest can come from a collar, a visible waistband or a different overlap. Use the individual garment details to choose the pieces that support the combinations you want to try.
