This is the Secret Wishes brand, sexy "Robin" costume. A 5 piece red/green/yellow polyester metallic dress, belt, fingerless mitts, and eye mask. This fabric is stretchy. Sizes measure as follows:                              Bust         Waist        Hips XSmall(0-2)-      30"-32"    26"-28"   30"-32"      Small-(6-9)-       34"-36"    30"-32"   34"-36"      Large-(14-16)-  36"-38"    34"-36"   36"-38"     Plus-(14-16)-     38"-40"    36"-38"   40"-42" * Because of the nature of this particular polyester metallic fabric, it has a tendency to stick to itself while folded in the package, and even though they were folded with tissue, there are still parts that stuck together, and when pulled apart leaves a slight discoloration, or loss of color. The costumes endure warm temperatures in the summer, leaving them with a slight tacky feel on the outside. This is the reason for the price reduction. The costumes are still cute and very wearable, and a great bargain for a one time wear.
