Bar the visible underpants, I like Steph's outfit. She looks very relaxed, and more importantly, happy. She's also not dressed in a way to upstage the bride, yet she looks radiant and serene.
I can see various trolls coming out and criticising her for not having a washing-board stomach (not on this board obviously but in other, darker more disconcerting areas of the internet) but I find it quite refreshing that Steph still has a bit of baby weight and hasn't dramatically lost tons to conform to looking like a model while her baby is still newborn, as so many women in the public eye do. I'm sure that given everything, her ultimate priority is Charles, the rest can simply wait, and good for her for doing so!
We've only seen her a few times since Charles' birth, but she's left me with a new-found admiration for her: becoming a mum really seems to have changed her, made her more relaxed and feel comfortable in her own skin

Gui looks a lot healthier too since Charles' birth. He seems to have lost weight (judging by the trousers)and lost that red face that he had for many years. Together they seem more of a couple than ever, and more assured and comfortable with each other. I'm cautiously getting more hopeful for the future of the LRF (and perhaps becoming a Gui and Steph sugar!)
