Well now I feel folish. I was looking at a video on Youtube about wardrobe basics, and the woman said a "black silk cami" was a basic for her, and she showed the Aritzia one. I guess she couldn't find a black silk cami either seeing as she had to show a non-silk one for her example!
Don't be silly. The real problem is, that some retailers have 100% polyester tops listed as silk.
Betina, I said order those jeans, as hemming skinny ones shouldn't be a problem.
