When you bring home your new bundle of joy, you'll need to have a closet or dresser stocked with clothes to fit his tiny frame. Many parents like to dress their sons in classic boy colors such as blue, brown, or red. Sports-themed clothes, as well as those featuring vehicle motifs, are popular for little boys. If you prefer gender-neutral clothing, stick to yellow and green pieces. For a timeless look, shop for clothing in solid colors, stripes, or plaid patterns.
