Not for me, this answer was easy!
1976–the year of Halston! He designs uniforms for many high profile commercial businesses. Braniff Airlines, Avis Car Rental and The Girl Scouts (could this be why I always wanted to wear my uniform?) Most prestigious uniform request came from the US Olympic Committee, he was asked to design the US Olympic Uniform! He had just released his first fragrance and was riding high as a top American Designer.
I hope your ID4 is the best ever and you have as many fond memories of this wonderful holiday as I do!
