I have wore these bras for years and the last 2 times I have purchased I had to return because they are too small and the straps don’t have any elastic so you can’t even get it on.
Before this I wore the Wacoal "Awareness" bra for probably 10 years. I ordered this style on a whim during the Anniversary Sale (because the Awareness bra rarely goes on sale) just to see how it felt and it is SO frickin' comfortable- WAY more comfortable than I thought it would be. The underwire doesn't poke into my armpit, which the other style would do occasionally. It really fits like a glove. The only reason I'm giving it 4 out of 5 stars is that the material relaxes with wear faster than I'd like. Within a few days of wear it's too loose to wear any longer. The upside is that this style is cheaper than the "Awareness" bra and it DOES go on sale so I bought a few, so I'm never without a clean, supportive one.
This fits perfectly and is so very comfy. I had it on all day and forgot it wasn’t a sports bra. Usually, I can’t wait to take my bra off, but I didn’t even think about it with this one. The straps did not slip once, either. In fact, this was my second one because I loved the first so much, I ordered another color.
