A bodysuit with a square neckline and a button closure from the sub-brand Babaton (a popular line of the Canadian brand Aritzia). This is a basic model from the Contour collection (in particular, the Contour Squareneck Bodysuit or Contour Tank Bodysuit), which is known for its double elastic fabric with a tightening effect, which fits perfectly on the figure and creates a "second skin" silhouette.
