A gathered frock for kids in a peach color with a print sounds delightful! For such a design, you might want to choose a soft, flowy fabric like cotton or chiffon to create a comfortable and airy feel. The gathered waistline adds a cute and feminine touch, and the peach color adds a subtle sweetness.

As for the print, you could opt for something charming and playful, perhaps floral patterns with shades of peach, pink, and green to complement the base color. This would give the frock a cheerful and youthful vibe. Consider adding some additional details like a bow or ruffles for extra cuteness.

Overall, a gathered frock in peach with a whimsical print would make a lovely addition to any little one's wardrobe, perfect for parties, outings, or everyday wear.
