23 Captions For Your Sister's Wedding When She's No Longer A Miss, But Always Your Sis

Being a bridesmaid is so exciting, but when the bride-to-be is your sister, that's when things are taken to a whole new level. You love your sister endlessly; she's your best friend since day one, and you've done basically everything together. Now, it's time to take on a brand new adventure — aka, prepping for her happily ever after. Along the way, you'll have sisterly fun on the bachelorette party and through the whole planning process, which is why you need captions for your sister's wedding to document all the memories.

It's not every day you get to see your BFF say, "I do," so you'll want to remember everything. From the shower to the reception, you'll be in charge of taking lots of pics and videos. When the time comes to draft up the perfect post to show how much you love your sis, you probably already used most of your best material for the maid of honor speech you're giving at the reception.

That's where I come in with these 23 wedding captions that are perfect for sister selfies on the dance floor, and everything in between. They're the right combination of sweet and clever that show just how much your sister and her happiness mean to you.
