One might ask oneself why one would crochet in 3ply? And I would respond that it's just so delicate! It's gorgeous. Wearable. Traditional. Victorian. If you like babies, then presumably you like them in frilly white things? Well, this is it! Enjoy.
This pattern has been sampled in King Cole Big Value Baby 3ply, and you'll need a 3mm crochet hook along with buttons for the jacket and a ribbon for the bonnet.
