Malina/Mo, I'm such a casual girl myself that I can probably live in three pairs of loose cropped pants/capris, 5 short T-shirts and 2 loose pillowcase tops for six months of a year --- and I did pretty much just that for most of the last two years! From that perspective, I find *your* casual style such a learning experience that I'm sometimes too awed to comment
And I do agree, casual that is fabulous is not only harder to pull off, but harder to appreciate as well, because to some people (and I say this only because I've BEEN guilty and sometimes still AM), casual is hardly even 'dressing up'. Ironically, perhaps people think it is 'too little effort' to dress casually, when it is harder to hold the line and not slump into frump? Though I have to say I hadn't noticed that tendency as much on YLF as on some other sites. (That said, on reflection, I've wondered whether greater appreciation of my casual Indian outfits sometimes comes from their more 'exotic' nature compared to my casual Western clothes.) And while I can see that it makes a positive difference to appearances, sometimes suggestions can tend to 'dressy-fy' an outfit that started out -- and intends to stay -- casual.
Now to your current outfit, I'm with Una in asking that you consider a closer colour for the underlayer. I love the tonal effect of this outfit, but the issue is that the switchover band is hitting at a point where it is suddenly widening your hip and making the top and bottom ends of you narrow by contrast! It wouldn't happen if the sweater were just a bit longer. So de-emphasizing the hemline seems a good idea in this case. (Alternatively, if weather allows, a longer jacket over the sweater, toning with the pants, or maybe an overshirt rather than a layer under?
