For each of the seven blouses, she has a choice of five skirts. Therefore she has 7 × 5 = 35 7\times5 = \boxed{35} different blouse-skirt outfits to choose from.

For each item of list 1, she can choose 1 item from list 2, and since list 2 has 5 items, she can choose 5 items for each of the 7 items in list 1... Giving 7 * 5 = 35
