Toddler boy clothes for fall can start with the shirt he already likes. It's easy to add a layer. Aimama V-neck cardigans are 100% cotton. The corduroy pants have an elastic waist and front pockets, with sizes from 12-18 months to 6 years across the available options. You'll also find sweatshirts, button-down shirts and tees here, alongside baby basics and clothes for older boys. Check our size guide first. Compare the length with a pair that fits now, especially if you usually need to roll the cuffs.
