Try Nordstrom or Macys or another department store Nicole. They will inevitably have tons of tops to try on. The nice thing about skinnies/straight legs is that you can fold them up to see what they'll look like at the right length. Also bring the shoes you plan to wear with them, since skinnier leg openings show more shoe...that might also be the answer to your disappointment at having to cover up your shoes.
I think you would look great in that Tulle top and some straight skinnies. I always like to try and find pieces that not everyone can pull off, but that *I* can pull off...if that makes sense. Most people wouldn't be able to wear that Tulle top, but you can, so I would go for it.
