[TO ADD] [GT] Female harem pants not in the game

According to the promotional images, female sims should have gotten harem pants just like men, as can be seen on the blonde girl in the center of this image: http://images.designntrend.com/data/images/full/68374/the-sims-4-get-together.png?w=780

I looked everywhere in the game (including buying all clothing-related club perks and maxing DJ/Dance skill) but cannot seem to find them.
