This might be getting a tad personal, but I really do not love wearing a bra. Not that I ever go au natural when inappropriate, but I find every way to not wear an uncomfortable under wire that I cannot wait to take off at the end of the day. A soft, unwired, camisole option is what I usually grab first in the morning. These options tend to not be the most supportive things in the world, but they are getting better. I love the color options available and how they are being incorporated into a look instead of hidden.
Victoria's Secret Pink carries some lovely bralettes that look fantastic peeking from underneath a tank top, low v neck dress, or open back top that actually give you some support at the same time. I have been wearing them all summer.
The camisole options are so pretty.
And I love the racerback option.
