Dress for a Christening?

[Haahoooo]

Help please!

DS is being christened in a couple of weeks time and after months of wearing jeans and t-shirts I'd quite to wear something elegant and feminine.

I'm 5ft7 and size 12-14, blonde. Would love something that's suitable for breastfeeding and hides the tummy area a bit.

Normally like Jigsaw, Phase Eight, LK Bennett but prepared to try something else.

Prepared to spend between £100 and £200 especially if it's something that I could also wear to the office later.

TIA

Was thinking of this one maybe:

Thank you very much jimmy! I like the blue one and the brown one in terms of design / shape. I am not sure if I have the courage to wear such a bright blue though. Typical I like the most expensive one best .

Thanks for the advice!
