I own one suit, other than this one. It's a black Theory suit that I've had for a couple of years. The problem is that I bought that Theory suit when I was thin, so unless I'm on my A game, them pants ain't zippin ya'll.
This lavender look is from JCrew. The blazer and pants are sold separately. If an all lavender look is too over the top, you could get either the pants or the blazer and slowly start to work it into your office rotation. Surprisingly, lavender is easy to pair with most of my neutral pieces for work. I get so many compliments on this suit. It's different, but not lime green or anything crazy.
