I went on a Tuesday close to noon and they were not very busy. The associate helping me was very thorough and professional. We spent a long time going through different bras that generally fit my "black everyday smooth" description. I ended up going from thinking I was a 34B (what I used to buy) to a 32C/30D (what I started buying for the last year realizing the rib band was always too loose on my bras).
They have a good selection although I wish I could've found something quite seamless and simple. However, I have to say what I brought home was still a smooth cup and the bit of lace was super sexy.
