1. A portable multi-fragrance compositional dispensing system comprising at least an aqueous based composition and a volatile solvent based composition, wherein the system comprises at least two separate containers, wherein: (a) a first container that contains the aqueous based composition, and a first dispenser operably connected to the first container and incorporating a first exit orifice, wherein the first dispenser is in fluid communication with the contained aqueous based composition and is a spray dispenser or a non-spray dispenser, and wherein the aqueous based composition comprises from about 0.1 wt % to about 95 wt % of water and from about 0.01 wt % to about 50 wt % of a plurality of microcapsules, wherein the wt % is by weight of the total aqueous based composition; and(b) a second container that contains the volatile solvent based composition, and a second dispenser operably connected to the second container and incorporating a second exit orifice, wherein the second dispenser is in fluid communication with the contained volatile solvent based composition and is a spray dispenser or a non-spray dispenser, and wherein the volatile solvent based composition comprises from about 0.01 wt % to about 98 wt % of a volatile solvent and from about 0.01 wt % to about 30 wt % of a first fragrance material, wherein the wt % is by weight of the total volatile solvent based composition. 2. The portable multi-fragrance compositional dispensing system according to claim 1, wherein: (i) the first dispenser is a spray dispenser and the second dispenser is a non-spray dispenser; or(ii) the first dispenser is a non-spray dispenser and the second dispenser is a spray dispenser; or(iii) the first dispenser is a non-spray dispenser and the second dispenser is a non-spray dispenser. 3. The portable multi-fragrance compositional dispensing system according to claim 1, with the proviso that both the first dispenser and the second dispenser cannot be spray dispensers. 4. The multi-component fragrance dispensing apparatus according to claim 1, wherein each of the spray dispensers, if present, is independently selected from: a propellant-driven dispenser; a mechanical spray finger-operated piston pump dispenser; a trigger-actuated piston-pump dispenser; other mechanical or electromechanical pump systems; a piezo-electric spray dispenser; an electrostatic spray dispenser; a bag-in-can or bottle system (pressurised or not) dispenser; an airless pump dispenser; or combinations thereof. 5. The multi-component fragrance dispensing apparatus according to claim 1, wherein each of the non-spray dispensers is independently selected from: a propellant-driven dispenser; a propellant-driven dispenser including a foaming nozzle; a roll-on dispenser; a dropper; a dauber dispenser; a pen dispenser; a brush dispenser; a stick dispenser; a pipette dispenser; a direct application dispenser; a pump (including finger, trigger, and airless pumps); a bag in can or bottle system (pressurised or not) dispenser; a mechanical/electromechanical dispenser; or combinations thereof. 6. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the microcapsules comprise a core material and a shell that surrounds the core material, wherein the shell comprises a material selected from the group consisting of polyacrylates; polyethylenes; polyamides; polystyrenes; polyisoprenes; polycarbonates; polyesters; polyureas; polyurethanes; polyolefins; polysaccharides; epoxy resins; vinyl polymers; urea cross-linked with formaldehyde or glutaraldehyde; melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates optionally cross-linked with glutaraldehyde; gelatin-gum Arabic coacervates; cross-linked silicone fluids; polyamine reacted with polyisocyanates; acrylate monomers polymerized via free radical polymerization; silk; wool; gelatin; cellulose; proteins; and combinations thereof. 7. The portable multi-fragrance compositional dispensing system according to claim 6, wherein the microcapsules comprise an oil soluble material that is selected from the group consisting of: mono-, di- and tri-esters of C4-C24 fatty acids and glycerine; isopropyl myristate; soybean oil; hexadecanoic acid; methyl ester; isododecane; and combinations thereof. 8. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the microcapsules have a volume weighted fracture strength of from 0.1 MPa to 25 MPa. 9. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the microcapsules have a median volume-weighted particle size of from 2 microns to 80 microns. 10. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the aqueous based composition further comprises a second fragrance material encapsulated within the microcapsules. 11. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the aqueous based composition is essentially free of a material selected from the group consisting of: a propellant; ethanol; a detersive surfactant; and combinations thereof. 12. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the volatile solvent based composition is a sprayable liquid, and the aqueous based composition is a formulation selected from: mousses; gels; solids; creams; lotions; ointments; solutions; emulsions; films; and combinations thereof. 13. The portable multi-fragrance compositional dispensing system according to claim 1, wherein the volatile solvent is a branch or unbranched C1 to C10 alkanyl, alkenyl or alkynyl having at least one alcohol moiety. 14. A method of providing a longer lasting fragrance, the method comprising: (a) providing a portable multi-fragrance compositional dispensing system according to claim 1;(b) dispensing a dose of an aqueous based composition to a situs; and(c) dispensing a dose of a volatile solvent based composition to the situs; wherein the aqueous based composition and the volatile solvent based composition are dispensed simultaneously or sequentially, in either order.
