Do you have the Jag Jeans? I have a straight leg style from them and really like them.
Here's a couple of ideas (and no, you don't have to tuck unless you want to - love that option myself).
I picked these off Nordstrom site just as style examples:
A slightly fitted wrap style : http://shop.nordstrom.com/s/ni.....tback=3591
A blousy but banded bottom style: http://shop.nordstrom.com/S/pl.....tback=2850
A peplum style:

You could do a more traditional blouse and just leave it untucked but for me to wear that way, it would have to be pretty tailored and hemmed to just cover part of hip and belly and not be too loose and drapey. I also like to do a tank and cardigan or a slightly loose tank and short/hip length blazer with trouser jeans.
Does that make sense?
