I just had the most wonderful experience at White House Black Market. I have never bought anything in this store before and actually have only been inside on a single previous occasion. As I was wandering around the mall depressed that it looked like (yet again) I would have to talk myself into a suit out of the Junior's Department at Belk, I went into WHBM on a whim. I told the clerk what I needed (a conservative black suit in a REALLY small size) and she told me to browse and she would pull things for me. 5 minutes later, she showed me to a fitting room with several beautifully tailored black suit pieces in, wait for it, SIZE 0 and 00!!! Every single thing fit me off the rack, except that I need to hem the pants and they only had the jacket I liked in 0 and I needed 00. The salesperson offered to order it for me and have the jacket delivered to my home free of charge. I walked out of that store with renewed faith in the American shopping experience. I ended up with size 00 black trousers, size 0 black skirt and a soon to arrive size 00 black jacket. The detailing on this suit is beyond anything I could have hoped for. I felt so confident in it. And the best part -- all 3 pieces totaled just under $300.
So, for all you petite ladies, check out WHBM. The suit I bought is not pictured on their website, but I think their stock should be similar from one brick and mortar shop to the next. Good luck to all of you.
