I need to get some pieces for a convention in April. I want to get a couple of tops and something to wear over them. Has anyone else purchased from Lands End's business line before?

I was thinking about getting this dress shirt but would like to have an option for layering. We typically buy shirts in the Sea Blue color: http://ocs.landsend.com/cgi-bin/ncommerce3/ProductDisplay?Krypto=BoP%2B4DFs4leOeEuQB2003DBnbv61nsd1sdA0a28auuSalRi7v5zOkOPeo%2BGl9dxewrjk0W3y57o%3D&red_store_name=corpsales&red_store_type=1&style_number=419464&productId=3051

Can you help me figure out what would look best for layering? I don't like 3/4 sleeve shirts and I don't like ruching or ruffles on shirts. If it helps, I'm a size 8, 36B bust.
