I have been wearing Wacoal bras for years because they offer the best fit, and this style has become my all time favorite. However, when ordering my usual size from Amazon, I immediately noticed it was somewhat "snug". I thought probably it just needed to be washed, & would probably stretch out after a bit. However, it is still just as tight. Then, this morning on NPR, during a segment on sizing, there was something mentioned about how imported garments that are shipped from other countries are not always sized appropriately for US sizes. Bingo! This must explain it. My advice, be wary of ordering expensive products that you can't try on first, or be prepared to return it.  Don't think that just because you order the size you usually buy, that it is necessarily what you're truly getting!
