Thank you for looking. These are 2-way half pants with detachable shoulder straps ♫ They can be worn as suspender pants during babyhood and as two-tuck half pants around age 3, allowing them to be worn for a long time. The waist also has an adjuster for fine-tuning the size. The official recommendation is for ages 1-6. They were included in a MARLMARL set purchased in 2023 but have never been worn. There are no pets or smokers in the household. They will be shipped compactly.
