I'm gonna peg it to her switching to requip. If other Masters can do it, makes sense she, being a genius, can do it.

Her internal monologue was prolly like "Damn, I wanted to look cool so I imagined up these clothes, but that last headache affected my concentration; let me look at the similar designs in the windows and use them for requip. I will hide the slight difference with illusions!" :D

Though that's just being optimistic. It's merely a humorous oversight. XD
