Please help me figure something out: do I need to look softer at work? This is the back story....

So as many of you know, I started a new job six weeks ago. My new job is similar to my old job, which is helping to manage a mental health program of about 50 people. However the standards of attire are different. Jeans are okay every day. My counterpart, the other Manager, wears jeans and Cons (he does this in a stylish, well put together way). My boss wears flowing garments accented by stunning hand-knit (by her) pieces. I decided just to wear my normal work clothes and to observe my own self-imposed Casual Friday. So Monday through Thursday I wear dress pants and booties with a silk shirt or a nice sweater, with a blazer and a warm scarf because my office is freezing. Sometimes I wear a sheath dress or pencil skirt with tall boots. Plus blazer and warm scarf.

Nobody is dressed like I am, except for the higher-ups who are in another office 10 miles away. It's not my goal to out-dress everyone. But (1) those were the clothes I had; and (2) I thought it wasn't all bad to dress nicely given that I was new in a management position.

Today I wore something a little different, a fit-and-flare surplice dress with a toning cardigan and tall wedge boots. (This is a dress I feel frumpy in but I get so many compliments on it that I've kept it in rotation.) I'd worn the dress before, but today my boss noticed it. "Oh! You're wearing a dress! Usually you're in suits!"

Note that (1) She's only seen me in a suit once, at my interview in July; (2) I've worn the dress before; and (3) I wear jeans every Friday. Also, come to think of it, when I wore my ink blue lace pencil skirt, she said I looked nice.

Her remark got me thinking. Do I look like I wear a suit every day? Is this a bad thing? Do I need to wear flared dresses more? Does she *want* me to look softer? What kind of impression am I making? What should I wear? How am I going to keep warm?

To me I am dressing appropriately. To me my image is not overly harsh or high-authority. Am I wrong? Is it foolish to have an image that's completely different from everyone else's?

Any thoughts? Thank you so much!!!
