Browsing Halloween costumes with my 8-yr-old daughter, I found this under the tab labeled "Careers." Apparently Party City doesn't believe girls should aspire beyond "Celebrity Starlet" or "Pop Star." When I questioned Party City about this on Twitter, they responded: "Those are some of our more feminine Career Costumes," and then provided a link to their wider selection of general costumes.
While there are admittedly some stinkers in the selection of "Career" costumes for boys (doesn't every parent hope his/her son will grow up to be an "Escaped Prisoner"?), they still have the option of dressing up as police officers, firemen, air force pilots, astronauts, soldiers, and doctors.
Party City recently opened in my town of Ithaca, NY, and my kids and I *love* the place. It's bright, colorful, clean, and cheerful - not to mention affordable! I planned on buying my kids' costumes from there - and probably still will - as an alternative to the temporary costume shops at the mall where (I believe) some of the costumes can be too scary or visually inappropriate for young kids. I just wish Party City offered a better selection for my daughter. PS - She wants to one day go to school at Cornell and be a vet when she grows up. NOT a "Cupcake Cutie." Incidentally, a search for "vet" turns up this.
