Baby linen Short suspend her outfit with bowtie

Super cute like brand new, worn for 30 minutes to take a picture once. Gray short with suspender set. Also Comes with the bowtie with Velcro Closure & hat. Received as a gift, ordered from Etsy. Does not say size inside outfit. I am pretty sure that this is a 3 to 6 months. My son wore at 4 months old he was average size.
