Floral Prom Dress, £135, Needle & Thread
She might not be one of the wedding party, but this floral, puff sleeve dress will certainly garner her attention. It has an elasticated top and satin bow around the waist so you can adjust it to get a comfortable fit.
Pleated Jumpsuit, from £30, Next
If she's refusing to wear a pretty dress, why not compromise with this pleated, floral jumpsuit? Made of light chiffon, it will keep her cool and the cutout shoulders give it an edgy, modern feel, while still being wedding appropriate.
Cat Face Handbag, £8.99, Amazon
She might want to take some trinkets and toys to keep her entertained on the day so treat her to a cute, little bag of her own. This pink cat crossover bad can be worn over her chest, leaving her hands free for confetti-throwing and cake-eating.
Monnalisa Pearl Handbag, £115, Childsplay Clothing
Or delight her with this adorable pearl handbag, big enough for her confetti and snacks.
Star Hair Accessories, £11, M&S
Finish off her look with some adorable hair accessories to keep her looking neat and tidy, at least until after the photographs. This multipack includes a sequinned star hand band and unicorn, star and rainbow hair clips.
Best Boys' Wedding Outfits
Boys can prove tricky when it comes to finding wedding outfits. You need to find a balance between something that is smart, and something that they will be comfortable in too. It's worth trying to be smart on one half and comfortable on the other so, if you give them a shirt, you can go more casual on the trousers or, if they are in smart trousers, choose a top that's more relaxed. Accessories such as bow ties and braces often get taken off through the day but as long as they keep them on for the ceremony, that's a result.
2-Piece Shirt and Trousers Set, £17.99, H&M
This plaid shirt and cotton trousers set looks smart but there's plenty to make children feel relaxed while wearing it. The trousers have detachable, elasticated braces, a fake fly and an elasticated waist, while the shirt is made from soft, brushed 100% cotton.
Toddler boy shirt and shorts set, £28, Jojo Maman Bebe
Finding toddler wedding clothes is especially difficult but this shirt and shorts ticks all the boxes. There's a popper opening for easy-peasy nappy changes, elasticated waist and integrated shirt bodysuit so they stay tucked in and smart all through proceedings.
Checked Shirt, from £12, John Lewis
For boys, the best kids' wedding outfits aren't always the smartest ones. This checked shirt can be dressed up with some chinos or dressed down with a pair of jeans. Made from Better Cotton Initiative cotton, the fabric feels soft and comfortable so you won't hear any complaints.
Monsoon Boys' 4-Piece Suit, £58, Very
Perhaps your little man likes to be a bit debonair. If so, this four-piece suit might be just his thing. This boys' wedding outfit includes a bow-tie and waistcoat and will keep him looking stylish and smart through to the end of the ceremony (at least!)
White Oxford Shirt, from £11, Next
Boys don't have to go over the top to be the best-dressed kid at a wedding. A simple white (ironed!) shirt is often all they need to look the part. This Oxford shirt is button down and can be worn with simple black tailored trousers to finish off the look.
Mango Kids' Chinos, £15.99, John Lewis
Chinos are a staple of kids' wedding outfits and these ones come in three different colours: khaki, navy and light beige. Made of a cotton blend (98% cotton and 2% elastane), they feature two side pockets and two welt pockets so there are plenty of places to hide any knick-knacks they might find during the speeches.
