Cellulite is characterised by a dimpled skin surface (like orange peel).
The fat cells we have under our skin are located in chambers which are separated by connective tissue septae. The septae are anchored rigid fibres that do not stretch with skin if the volume within the walls of the chamber increases (as occurs if we put on weight).
So when the fat chambers become distended by enlarged fat cells and by retained intercellular fluids, expansion occurs beyond the length of the vertical septae, pushing up the skin surface and resulting in a dimpled skin appearance.
