What Can I Wear to a Wedding While Pregnant?

If you are invited to a wedding while you are expecting it is important to keep in mind that your bump may have grown by the time the wedding day arrives. Ensure you buy a maternity wedding guest dress that has enough room to cater to this - baby doll and wrap styles, ruching, stretchy fabric and loose silhouettes are great features to look out for.

You don't have to confine yourself to specific maternity collections (although lots of high street shops have amazing options), many maternity clothes for wedding guests can be worn well past the wedding date for seasons to come. 

Now you've got the wedding guest dress sorted, what about finding the perfect gift for the happy couple? If they're eco-conscious (or even if they're not!), you're bound to find loads of ideas in our sustainable wedding gift guide
