This bra is heavily constructed of materials with minimal stretch ... So I was skeptical about it being comfortable for yoga.  I tried it tonight in an aerial yoga class with lots of bending, stretching, twisting and inversions (hanging upside down).  The bra performed well and was more comfortable than I expected.  No restriction of breath or movement.  While not as comfortable as my Berlei bra that is all soft, stretchy material, (but old and in need of replacing) with this Glamorise bra I had no concerns that I might be over exposed in inversions and I did not need to readjust it (or the "girls") as it stayed in place very well.  I did size up one cup size from the F that I normally wear in Glamorise Sports bras to a G because I was looking for freedom of movement over firm support.
