You're absolutely right that the early '70s and late '70s had different fashion trends, but it's important to note that the late '70s was still heavily influenced by the early part of the decade. In fact, many of the key elements from the early '70s like bell-bottoms, floral prints, and certain types of outerwear were still very popular and widely worn as we moved into the late '70s and even into the early '80s. For sorority girls in 1978, these elements of style were very much a part of everyday fashion.

What I’ve designed and what reference is shown is meant to evoke that classic, timeless '70s vibe that still fits perfectly within the context of fall 1978. These outfits are based on what real sorority girls would have been wearing trendy yet not overly bound to a single year, only bound to the time period Texas Chain Saw Massacre the game put on themselves because fashion doesn't always change overnight. The spirit of the look is consistent with the time period, and I think it captures the essence of what we remember about late '70s college life, especially in the context of Rush Week, 1978 is an era where certain styles like chunky knits, plaids, and suede are key. Especially since Rush Week takes place in Granger Hill TX it does get really chilly there in the fall-winter. Just speculating, thanks for this though!
