Most unflattering panty lines possible!  I wear a size 4 or 6 depending on brand so I ordered these in a size small.  They are not tight, in fact I like a bit more support from my running underwear, but that is not my primary issue with these.  The only place they are tight is the leg openings.  They create the most obvious and horribly unflattering panty lines imaginable!  They arrived and I washed them so I could wear them today.  I put them on and thought I would just go ahead and wear them for a run before passing final judgement but honestly I caught sight of myself in a mirror and decided I could not go out in public.  I can't make myself throw out brand new clothing so for now I plan to keep them to wear with loose flowy skirts where the weird panty lines won't show.
