Question: do wacoal bras run small?
Answer: In my experience, Wacoal does not run true to size. Their particular bras vary in fit depending on the bra. The Retro Chic is a very deep cup, so I usually size a cup down for that. However, the Amazing Assets runs small in the band and the cup and I can't even think of squeezing in the 38DD or 38DDD.
