Ordered a M. I’m 5’6 160 pounds. I’m your averageee. Average 34/36C. Size 8-9 usually a M bloated days a L. dress size small/med…swimsuit usually M. Everything mostly MED! Very pretty dress, material is soft and “dreamy “ . If you have smaller boobs than me this size is not for you. I have perky full C almost D cups. The fact you can’t adjust the straps it was way too big on top. I had to take the straps and tie them together in the back to make the dress fit . Hope this helps!
