Spanish-based clothing retailer Mango is moving into 600 JCPenney stores across the states by Fall 2010.

With both Charlotte Ronson and the Olsen twins stationing their own lines there, the department store seems to be making its way up the fashion industry ladder! While Mango has already set up 12 stand-alone shops in the US, it is nothing compared to its international number at 1,200; it is clear that the partnership is aimed at broadening its American presence.

Although the I Heart Ronson line isn’t too bad, there was nothing special about that line nor the Olsenboye range. This makes me wonder if Mango will be altering their clothes to fit the JCPenney look once they’re in the stores—the last time I ever step foot in the department store, I’m fairly sure I didn’t see any sweaters priced at $70.

Either way, I’m more concerned about having to prepare myself for a bombardment of Scarlett Johansson ads when I do my back-to-school shopping!
