oh geeez, lol...i skipped right over that, forgot all about listing the size. I am glad you brought this to my attention. Though when I went and looked for the size today, there was no tag...I must have cut it off. Though I do know that I am a size 5 in pants as well a dresses and shirts usually small or mediums, so this nursing top fit me well. So if you are a slim, like a size 5, the top should fit you fine.
