I purchased this brand new over the summer. It is a size M/28" waist. I am a size 4 & it fits me snug. I did try it on, but I never wound up actually wearing it - it definitely sucks everything in! I removed the tags, fully intending to use it one day, but just never have. This is the brand all of the vintage/retro influences love for its historical accuracy in creating 40s-50s style undergarments. Will accept reasonable offers!
