Greta dress by Pinup Couture
Apart from looking beautiful, the best thing about Pinup Couture (or Pinupgirl Clothing, as they used to be known) is that they are so low maintenance. You can even machine wash their stuff! This dress is so comfy too, it has enough support that you don't need a bra. I am a C cup and i can literally jump up and down without people realizing I'm braless or getting that horrible jolting feeling.
