This slip fits under any of our waisted gowns. It is made of cotton and is very light weight. 2 buttons close up the back. If you need a slip for any of our gowns make sure the gown is waisted style and order the same size as the gown you’ve picked. If you are ordering a slip for a gown you already have please lay the gown flat, measure the middle of the shoulder to the finished length and measure under the arms from side seam to side seam.
