Shirts are nice if you ave random jeans for the toddleedoo sitting around, or if you just happen to kinda hate a top to an outfit you got. And these two shirts are cute. The pink one on the right is from Nerdalicious. It's just the shirt and it's actually pretty cute.
The green one below is from Zoobatos. Neither of them come with pants. But this gives you more freedom to create your own styles with their outfits.
Bottom: Fluffy Panda - Mesh Sweater - Toddleedoo [BABY]
Right: [Nerdalicious] Pink Ladybug! Mesh Shirt - Toddleedoo
