These pink, giraffe, toddler girls pajamas are adorable! I believe I purchased the side 3-4years& they fit he great, she's 3.5 years old, so ifI say their true to size, if not slightly big, but that's ok, because they grow so fast! If recommend that jammies to any parent for there little ones! Great quality, stretchiness to the fabric but not see through. Washed (cool water) & dried great for me!
