$38.00This bra is amazing. I have the hardest time finding a strapless bra that I love. I have bought cheap bras and I have purchased realllllllly expensive bras, but this one tops it all. It stays exactly where it is supposed to and doesn't ride down. I also love that the back is a wide strap, so if you are "blessed" like I am, it supports you well. You can find this bra online, at Macy's and Dillards.
As far as regular bras go, I ADORE the Wacoal Embrace Lace bra. Warning: If you need padding, this bra is not for you. I need zero, so luckily, this bra works for me. It is so light and feels like you don't even have it on, which I love! I own this bra in three different colors. I hand wash them and they have lasted forever. They run about $50.00 each.
The Maidenform Firm Control boy shorts are a great alternative to a slip in the summer time. I love to wear these under my dresses or rompers. It's so light, so you almost forget you have it on.
I hope this helps when you are purchasing your summer undergarments! :)
