NEW Marimekko simple stripe tee unisex size 4Y (fit is 4-6Y) - have 2

For a family photos shoot I bought two of these one in size 4Y and one in 6Y for my boys - the shirts are literally the exact same size lol - I'd say they would better fit a 4-5y old but my kids are big...the two sizes were made in different countries so I'm assuming that's the discrepancy in sizing. We never ended up wearing these so they are BRAND NEW. *please check out my closet - TONS of great kids clothes have been adde this week (Janie and Jack, Lilly Pulitzer, Baby Gap, Marimekko etc)
