You know I'm going to say I love it.
You do not have to stick strictly to matching sweater material, Eva. Try it with a cami or a silk blouse or a finer knit wear. Anything goes. Do try this with cream or white top too.
I think this is the color that Angie mentioned may be hot this fall? Lilac?
Because the bolero style closes at the bust, it draws the eye towards the bust. So for work I would stick to a modest neckline just like you've chosen - for a hot date, you could go lower. Depends on your goal! I wear my identical pastel pink bolero with a particularly sexy dress I own, one with a sweetheart neckline that flaunts my cleavage, for hot dates with my hubby.
I just want to add that I have regular cardis too - I'm just on a cropped jag at the moment!! I like the look because I think it balances me out proportionately, makes me look taller, and draws the eye up to my natural waist, which is rather high.
