Fit is OK, but still, I find it a bit short. My problem with peplums is the same: too high (almost empire on me) waists and never enough length +/_too much of the flare.
I think Angie was buying and wearing it more for the perfect scale of the stripes, the good, quality and the non wrinkly thicker fabric which has some shape. Think, it has to be kind of a dressier rendition of a striped tee in her wardrobe. Guess is also very comfy from waist dowtn, so perfect fort travelling :-). We can also see she styled it to a casual setting with a casual distressed jean and with a denim jacket layered on+ colorful scarf-I mean it is there, but we can barely see the peplum and the classic cut of it it. She styled it in a non classic way so did a perfect unexpected juxtaposition there.
So, if keeping, I suggest the same styling for you, too, for avoiding the sweetness, wich I know is NOT your style at all!
ETA: Skirt and peplum, hmm....not so sure for you.. Stripes on stripes will be too much, I think, but depends...we have to see. Then another ideea would be high waist cullottes, flares, or long dressy shorts :-).
