recessionista
n.— «A recessionista is simply some one who seeks fashionable items that are also inexpensive.» —“Fall fashion 2008: The year of the recessionista” by Debra Braggs Press-Register (Alabama) Sept. 9, 2008. (source: Double-Tongued Dictionary)
Here’s another citation from the New York Times, which defines recessionista as ““recessionista,” the new name for the style maven on a budget” (and the article quotes Grant Barrett):

And still another citation from a Philippine newspaper, which defines recessionista as “the recession-chic fashionista”:
