I was looking through the clearance rack near the fitting rooms while I was waiting for a room to be free, and came across the Lululemon Not so Deep V bras, they didn't have many choices as to size or color available because they were last seasons colors.
On the tag it says this bra provides moderate to medium support, I would say in reality as a wearer it provides no to light support, I am a B cup, so maybe for a smaller size woman it might add moderate support. I don't recommend this for anyone above an A cup if you are looking for hold and support, you wont get either! This wouldn't even add support for yoga!
It is mesh on the racerback and between the cup area or 'sweat zones' for ventilation, breathability and comfort. There are pockets in the cup area with removable pads that fit weird, and fall out.
My first time wearing this bra to the gym I felt like I needed to wear a real support bra under this one and just wear this 'bra' as a fashion item, I did wear it under a workout tank top with a built in shelf bra and felt that if not for the tank top shelf bra I would be looking totally braless.
I also couldn't stand the style of racerback, or the mesh it was very irritating. I am happy I bought this on sale for $14.99 and not the regular price of $42.00! I don't think I will ever buy another bra from Lululemon, not even just for yoga, I like to be covered and supported.
I also need to add that it flattens your chest, and just looks terrible, I don't mean you will look smaller, you will just look squished and pancake like.
