Congratulations on your promotion! You have a great sense of style (I snooped in your profile); don't lose that because you have to dress for "business". Do some vision questing for examples of what you'd like to wear (I like to keep a book of swatches and clippings) and then make some basics you can dress up. Look for a jacket pattern you like and some skirts/pants to go with. Maybe buy yourself a couple simple expensive suits that don't make you puke and make cool stuff to accessorize them. I got myself a basic suit at Macy's several years ago that I still separate out and wear. Keep it simple, but stay as cool as you are. Good luck!

Both Blair and Coldwatercreek have good prices in their closeout section and have business clothes in large sizes. Coldwater creek has splashier designs.

Also, saf-t-pockets.com has nice patterns - their 'getting to the point' jacket will dress up most plain dresses or pants and has several hidden pockets: webstore.quiltropolis.net/store...v2.asp
