Boys' long-sleeve tops form the basis of any wardrobe, no matter the budding trendsetter-in-question’s age. Look to our edit of designer boys' tops and polo shirts for proof. Burberry's British-inspired offering of logos and prints come in a medley of solid colourways and stripes, while a Stone Island Junior T-shirt will add a streetwear-scented spin to any look. But, if it's instantly recognisable designer flair he prefers, then count Emporio Armani Kids your go-to for designs with signature eagle motifs that come in handy multi-packs.
