I wear wacoal exclusively and was so excited to find this bra.  it seemed perfect! when I ordered these also discovered they were tight in the strap.  Ok, I can live with that.

But on both bras, on the FIRST wearing, the metal fittings that allow you to adjust the straps broke.  I simply took them to my tailor and had them stitched permanently together at the right length.

But I won't buy these again until this problem is fixed, and like others have noted, I'd go up one band size.
