I'm an ordinary sized woman in her forties -- I usually wear a size 6 or 8.  I ordered a medium.

This top fits great at the shoulders and arms -- it covers the bra straps and does not gap open.  But at the waist and hem, it is WAY too big -- I'm like the Liberty Bell bell wearing this top.

Ordinarily, I would like a LITTLE flare because, well... I'm in my forties and stuff settles.  But this top is just shapeless (contrary to what is shown in the photo.)

I am thinking about ordering a smaller size... but the fabric feels sort of cheap and I'm just not in love with it.

What I really like is the stripes.  But overall, this top is unshapely.
