Baby First Birthday Outfits

Baby's first birthday only happens once. Whether you're booking a professional cake smash shoot, throwing a backyard party, or keeping things quiet with a little celebration at home, the birthday outfit matters – it's in every photo, every video, every memory you'll pull out in ten years.

At Lulu Babe, our baby birthday collection covers girls and boys from newborn through to toddler, with styles that photograph well and hold up through a full day of celebrating. Many of the outfits here cross over naturally to christenings, naming days and family gatherings – so if you're dressing up for any special occasion, you're in the right place.

For the full party look, baby shoes and headbands are stocked separately under baby accessories.

Baby Girl Birthday Outfits

Our first birthday outfits for baby girls include knit rompers with embroidered "One" details, tutu sets with matching headbands, flutter romper dresses in tulle and lace, and "birthday girl" bodysuits – simple baby party outfits that still feel special.

Colours run from soft neutrals and blush pink through to ivory, sage and sunflower yellow – so there's something to suit every party palette, whether you're going pastel boho or bold and bright.

Baby Boy Birthday Outfits

Our first birthday outfits for baby boys include bow tie and suspender sets in a range of colourways, tuxedo shorts sets for a more formal look, and "My 1st Birthday" suspender sets that come ready to wear. These gentleman-style outfits are popular for first birthdays, christenings and naming days. Pair them with baby shoes for a dressed-up look, or keep things simple for a more relaxed celebration.

Sizes & Occasions

Sizes run from newborn through to 3–4 years, so the collection works for first birthdays, second birthdays, and half birthdays too – some families do a small cake smash at six months, and there are options here that suit that occasion without being overtly "ONE"-branded.

How to Choose a First Birthday Outfit

A few practical things worth thinking through before you buy:

The weather. Australian first birthdays happen in every season – a knit romper that looks stunning in a Melbourne winter shoot is going to be uncomfortable in a Perth January. Check the fabric: knit and cord styles suit the cooler months, while cotton and muslin styles handle the heat better.

The photos. Cake smash photographers generally prefer solid colours or simple textures over busy prints – the cake and backdrop do the visual work. If you're booking a professional shoot, it's worth checking with your photographer before you order. The knit rompers and tutu sets in this collection tend to photograph particularly well.

The practical stuff. Snap closures at the legs make nappy changes faster when you're mid-party. Sets with separate pieces — bodysuit plus shorts or skirt — give you more flexibility if one part gets cake on it before the photos happen. If the outfit includes a headband, test it at home first.

The timeline. If you have a date locked in, allow enough time for delivery. It's always worth ordering a size up if you're between sizes – birthday outfits are often worn for photos first and parties second, so fit matters.
