Wear a red top and trousers, if you get stuck for red trousers get some red tights or try at a dance shop. Wear red shoes.
Blow up a load of red balloons and attach them all over the body and either wear a green hat or make one out of material or if you really get stuck some green hair spray will do.
To complete the outfit paint your face red.
And hey presto you're a strawberry.
Thanks to Victoria for this cute idea!
