I'm so surprised that some folks have a strong dislike for a whole range in a shop! As long as I like it I don't care where it comes from- ds has Primark, Mothercare, Next, Boden, charity shop finds, McKays, Peacocks, Feu Follet, Woolies, Monsoon, Gap, overseas brands- everything really. Think anyone would look a bit contrived if they only dressed in clothes from a certain list of shops.
I like to dress him like a little old man! Hand knits and cords, but not the knits in Monsoon (they are no better imo than the cartoon stuff what with all the silly pictures on!) He's 3.4 and has no real interest in what he wears so I can get away with what I like still
I also like the "grandaddy" long sleeved tshirt under short sleeved shirt look- Gymboree and Janie & Jack in the USA do some really nice retro print shirts and these always go down well.
Don't like any kids cartoony type prints on clothes, or slogans, happy with stripes spots patterns etc otherwise. DS suits earthy colours and looks amazing in baby pink, really bright colours wash him out though.
Agree that it is hard to find nice boys garb though, but it makes it more fun when you find something gorgeous!
