Both of these will be suitable as first camera. If your fashion photos are always shot outside with lots of sunlight and the photos are for personal use or perhaps posting to a blog then you'll be fine.
But if you're hoping to do any fashion shots inside in low light or in a studio then you would want to consider something with a larger image sensor (like a DSLR) and something with a hot shoe to take an external flash (or flash trigger).
I have no direct experience with either camera... so all I can really suggest is that you go to a camera store and ask to try both. Figure out which you find easier to use.
Good luck!
