The present inventive concept relates to a sealing device (1) for garments to sealingly connect an annular layer (3) and a wearable layer (5) to the sealing device (1). The sealing device (1) comprises an annular base (10) having an inner annular wall portion (12) and an outer annular wall portion (14), a recess (30) at least partly defined by the inner annular wall portion (12) and the outer annular wall portion (14), and an annular sealing surface (40) for circumferentially and sealingly connecting the annular layer (3) to the annular base (10). The sealing device (1) further comprises an annular sealing body (60) adapted to be locked into the recess (30) to circumferentially and sealingly connect the wearable layer (5) between the annular base (10) and the annular sealing body (60). At least one of the inner annular wall portion (12) and the outer annular wall portion (14) is provided with a plurality of sections (50, 52) in the circumferential direction, each section having a stiffness different from a stiffness of a neighboring section.
