The only thing to watch with stripes is your size versus the size the stripes make you look. Horizontal stripes will make you look wider, vertical will make you look thinner.
You can use it to your advantage to accentuate the bits of you that you like, give yourself a slim waist or an hour glass figure, just by playing with the fabric. Don't get very thin and cut it on the bias, you'll look like a walking tornado and don't ask me how I know!
Good luck and yell if you need anything.
