I bought this top in my usual size large and it is slightly big, but not so much that i would want to size down.  the material is slightly itchy, but i think that it's worth it because it's such a pretty top. i absolutely love the detail at the top.  it is beautiful!  if you wear a nude bra, you can't see the strap lines through the material.  i also love the coloring of this top.  this is a great top that i can see myself wearing with dress pants for work or with jeans for a more casual look.
