6/12 months in size I wore this set on repeat with my chunky 9-month-old — the white gauzy tank is super lightweight with a little ruffle hem and the matching floral bloomers have a comfy elastic waist and leg openings that hold a diaper in place. I always washed them gentle; the bloomers’ elastic is still springy and the fabric is soft. The white top has very faint wear/discoloration at the hem from sun and wash but no visible stains or holes. Great warm-weather outfit that layers nicely under a cardigan.
