We've become well versed in wedding season, but christening season is upon us too, and the question that pops up time and time again is what do you wear to a christening? Thankfully, there's no hard and fast rules on christening outfits for guests, but as with all similar occasions, there's something of an unwritten dress code for both men and women to adhere to.

For men, that usually means wearing a smart suit, or at least formal trousers and a shirt, and female christening guests should consider venue appropriate dresses, suits and sometimes, cover-ups and fascinators too. Read on for the dos, don'ts and christening guest outfit inspiration.

The floral dress: Karen Millen Georgette Belted Dress, £59.40 / $143.40

The polka dot dress: LK Bennett Esme Green & Birch Spot Print Dress, £224 / $356

The wrap dress: Phase Eight Philippa Wrap Dress, £111.20 / $200

The pastel dress: Nobody's Child Jacquard Halter Dress, £120 / $204

Is there a dress code for christenings?

Since christenings are formal occasions, usually held in a place of worship or a smart venue, a christening guest outfit should follow suit.

For women, this tends to mean floral dresses, usually below the knee; you can wear sleeveless or cami straps, but I think bandeau dresses would be a no-go – add a blazer or boucle jacket to keep it modest. A smart suit, skirt co-ord or even trouser co-ord works too.

The most popular style for women is a floral, floaty dress, but don’t overlook the more structured style of a shift dress, or the whimsical shape of a tea dress. I for one love soft silhouettes for a christening, like pleated skirts in playful prints, and off-shoulder shirred bust dresses in pastel shades with big puffy sleeves. Baring your shoulders isn’t banned, just be sure to make sure the rest of the dress is quite covered up, like a maxi length, and not too fitted either.

Just always remember that this is a formal occasion, and trainers and jeans are frowned upon.

How I chose the best christening outfits for guests

Modest dress: While it isn’t a no-go to bare shoulders or knees, an element of decorum should be remembered when dressing for a christening. The pieces I’ve chosen are all at least midi length, and feel modest even if a shoulder shown - nothing is too fitted or tight.

Colour: I’ve opted for spring, pastel shades or block colours in cheery shades. An all-black outfit isn’t normally seen at a christening, but can be woven in with trousers, skirts or accessories so I kept this in mind when choosing the edit.

Price: Most of the time, you’ll find occasion wear can be on the pricier side. With that in mind, I've made it my mission to include fashion across a range of budgets.

New in: I've picked from new styles at our favourite fashion stores.

9/9

Rixo Leyane Maxi Dress

Sizes available: UK 6 - 16

Shipping: £5 Standard Delivery 

Returns: Free within 14 days

Rixo is the cool-girl destination for vintage-inspired occasionwear, never too smart or stuffy but always pretty, both in pattern and design.

I chose this pink dress to highlight for a christening for the versatility of it. Great with heels, or flat sandals, and can be reworn with sneakers on a sunny day. 

Square neck dresses are particularly flattering for women with a bigger bust, and if you're on the smaller chest side, the ruching on the bodice will add a bit of depth.

Can I wear white to a christening?

Technically, you can wear white to a christening as a guest, however, it is traditionally the colour for the child being christened to wear, in the form of a christening dress or gown. It’s not unusual for the mother to wear white either – Princess Kate chose creamy, neutral palettes for the christenings of her three children, but as a guest to Prince Harry and Meghan Markle's son Archie's christening, Kate chose a rose pink shade instead and left white to mum Meghan.

As a guest though, it’s not really the done thing to wear white to a christening. I’ve been a guest at many of them over the years, and other than the baby and the mum, I have not seen a guest wear all-white or all-cream, other than as part of the outfit (ie. a jacket or top). So all-white outfits to a christening? I’d skip.

Can I wear black to a christening?

You can, but bear in mind this is a celebration, not a sombre occasion, so accessorise wisely. Black shoes, accessories and parts of an outfit are fine  to wear, as is a black dress or suit. I'd personally try to not wear black, and choose navy instead or opt for monochrome.

Why you should trust me

I’ve been to quite a few christenings in my years, including the christening of my best friend’s daughter, to whom I’m a godmother (to which I wore a long sleeve floral dress with velvet black sandals). Not only can I give you advice from what’s stylish, but also what’s practical – a lot of christenings will see you holding the child, or a child, and standing around for long periods during the service and post-service celebrations.

Along with my years writing about fashion, I’m across what makes a good christening outfit for female guests and even though I haven’t tried the pieces in this edit, have used my knowledge and expertise to bring you the best christening outfit inspiration.
