Inspire me please - outfit for DS for sibling's baptism

[ComeOnEileen11]

Obviously I'm not buying yet, with the current situation, merely planning.
My DC2 will be being baptised once this is all over and I'm looking for a smart outfit that's not a suit.
DS is 2, and DH doesn't like the look of the tiny version of suits. I'd like it to be fairly smart for the occasion of our DC2's entrance into our church family.
I loved the heritage collection that Mothercare did but that's clearly not an option. Something similar would be good, but I'm at a loss for ideas. I'm not really style oriented though .
Are chinos and a nice shirt/jumper my only option?

I've just twigged, I'm after prince George style clothed, without Kate Middleton's budget.

Anyone with any recommendations please?

Monsoon used to do linen shorts & waistcoats in stone or baby blue which looked smart but cute & comfy.

M&S have boys smart boys shorts and waistcoats.

John Lewis have a heritage collection, not sure wha

What age they go up to*

Sorry - posted before if finished the message

The collection is called the Heirloom collection

Matalan sometimes does bits I think fit that vibe. You have to buy them when you see them though.
