Well, they both look good on you, no surprise there, but I'm getting the feeling that you are a similar situation to mine a few years ago. I had a closet full of beautiful, classic (there's that word again!) items that sat there because I never reached for them, even in situations when they would have been appropriate. They reminded me too much of my former workplace uniform--classic trousers, pencil skirts, and blazers--compared to my newer things. Purging them seemed scary because I couldn't shake the idea that I might need to wear that uniform again.
I finally decided to put together one tiny capsule of a skirt, blazer, and trouser to allay my fears and then put the rest into a storage bag where I could retrieve them if needed. A few months down the road made me realize (1) I didn't have any situations where I actually NEEDED that uniform, and (2) more importantly, I never WANTED to wear that uniform.
Well-fitting, quality classics that look good on you are hard to purge because so much seems right about them, but, if they aren't what you reach for, they are really in the same category as any other style--miniskirts, super skinny jeans, snug tops--you've grown away from. We hang on to them because of the IDEA, not the reality or the functionality.
