    A preordered microwrinkle pattern on a metal-capped surface of a soft elastomer is employed to elucidate the elementary buckling phenomenon during strain-induced stripe rearrangement processes. The preordered one-dimensional stripe tends to align perpendicular to the direction of strain reversibly when lateral compressive strain is applied on the substrate at some angle φ with respect to the stripe orientation. For any value of strain, the film surface can be decomposed in domains containing stripes with two different orientations, namely the original and applied strain orientations. As strain is increased, the domains of the second type of stripes progressively grow and invade the whole surface. Interestingly, the domain shapes during growth are composed of parallelogram units that simply depend on φ and stripe wavelength. Moreover, domain growth proceeds in characteristic directions depending on the shape of the domain unit.
