30 Captions For When Your Sister Gets Engaged And It's Time To Pop The Champagne

One maid of honor coming right up.

Originally Published: 

Engagements are always exciting, but when your sister gets engaged, your excitement is on another level. The bond between the two of you is unbreakable, which is why you're one of the first people she calls to tell the good news — that's when the fun begins. The first item on your to-do list is the obligatory and congratulatory Instagram post. You’ve got tons of cute photos of the two of you together that you could share. You just need sister engagement captions to make posting easy.

You have about a million stories to tell, like when you played dress-up as kids and planned your Barbies' weddings. If left to write your own engagement wishes for your sister, you’d write an entire novel of how much you love her. The problem is a short and sweet sister engagement quote is preferable on the ‘Gram.

Save those big stories for when you give your speech on the wedding day, and instead, use this list of sister engagement quotes to caption your IG post. They are the perfect length for anyone scrolling through on Instagram, but also convey all the love you have for your sis. All you need to do is pick your fave caption, post, and get back to celebrating her happily ever after.
