An adjustable pelvic compression belt for the reducing the width of, and/or realigning, a users hips that is particularly adapted for post-parturition use. The belt may include an inner belt to be wrapped around the users hips and positioned below the iliac crest. The midpoint of an outer belt may be attached to the inner belt at or near the midpoint of the inner belt. The ends of the outer belt may be adjusted to cinch the inner belt around the hips of the user, thereby compressing the users pelvic girdle. Thereafter, the outer belt may be incrementally adjusted to further compress the users pelvic girdle resulting in a narrowing of the users hips. The belt is preferably worn within two to three months post-parturition or during a period in which relaxin is being administered to the user, and has a strength and thickness that facilitates use under garments.
