My girls love these St. Patrick's Day leggings. They are brightly colored and included an oh-so-necessary RAINBOW! It appears these leggings have a bit of extra length, but are a bit snug. This is my 3 and 1/2 year-old in a size 4. I bought my 5 year-old a size 5 (she's smaller and slighter than girls her age), that size was a bit snug on her too.
I bought the same size as all of the other Gymboree leggings my daughter wears, including the valentine ones, and these were super tight in the legs. I didn’t have a chance to wash them before she wanted to wear them, so they didn’t shrink. My daughter does love the bright colors and fun pattern. She didn’t complain they were tight once they were on, but they were definitely a different, less stretchy, material.
