6/12 months I used this for my toddler one summer — a lightweight white gauze tank with a little peplum ruffle and matching floral bloomers with an elastic waist and ruffled legs. I washed it after every wear so the fabric is soft and breathable. There are no holes or stains and the elastic on the waist and legs still holds its shape. Perfect for warm days or layering under a sunhat and sandals.
