Celebrity Bridesmaid Style Moments

1. Paris Hilton

Paris Hilton was a blue beauty as she acted as bridesmaid for YouTube star Lele Pons. Her satin blue bridesmaid dress boasted a ruched bodice with a sweetheart neckline, a thigh-high split in the skirt and a form-hugging design, making it a perfectly glamorous choice for the star-studded outdoor wedding in Miami.

2. Nicky Hilton Rothschild for Paris Hilton

That's hot! It's no surprise that as sister and bridesmaid for the pink-obsessed heiress, Nicky Hilton wore such an adorable, soft pink gown to Paris Hilton's extravagant wedding celebration. We absolutely love the oversized bow detail and the lace detail which complements Paris' dress beautifully.

3. Rachel Bilson

This beautiful pastel dress is the perfect bridesmaid dress for a summer wedding and Rachel Bilson wore looked beautiful as bridesmaid at her brother John's wedding! The silhouette is extremely flattering and we love how she left her hair fall naturally with just a delicate hairband to add detail.

4. Miranda Kerr

White gowns are a fresh trend when it comes to being a celebrity bridesmaid. Remember when Kim Kardashian had her sisters sport individual white dresses at her wedding to Kris Humphries? Miranda Kerr looks stunning in a broderie anglaise number with bright florals at her younger brother Matthew's wedding.

5. Sophia Vergara

Sophia Vergara was a vision in lemon for her friend Chi's wedding! This beautiful look is soft and uplifting on her, especially since yellow is often a tricky colour to wear.

6. Lena Dunham

Lena Dunham rocked a pared-back look for her best friend's wedding.

7. Pippa Middleton for Kate

This is the bridesmaid dress that rocked the world. Pippa Middleton stepped out for her sister's royal wedding in a bespoke Alexander McQueen gown.

8. Emma Roberts

Maid of honour Emma Roberts looked gorgeous in an ivory slip dress at her best friend Kara Smith's wedding in California. Beachy waves in her short hair and simple studs keep this look minimalist.

9. Eva Longoria

This bride chose a very special something blue for her wedding day - her bridesmaid Eva Longoria! She sported a beautiful, bouncy blow dry for her friends' Alina Peralta and Manuel Gutierrez's nuptials in Cordoba, Spain.

10. Lady Gaga

Pretty in pink, Lady Gaga looks effortlessly gorgeous at the wedding of her longtime makeup artist, Sarah Tanno, and Tim Stewart. For a sunset wedding on the beach, you can't go wrong with a dusky pink shade and in true Gaga fashion, her hair matched her dress - pink, silky, and flowing.

11. Beyoncé for her sister Solange

White party alert - Beyoncé stepped out as her sister Solange's bridesmaid in this figure-hugging, understated white dress with towering statement heels. With her hair is tossed in a natural curl and her accessories are beautifully simple - a single bracelet and shiny necklace - she was the very picture of effortless style.

12. Rihanna

Now this is how you do mix-and-match bridesmaid gowns - each and every bridesmaid here is a vision in purple. In particular Rihanna who reported for bridesmaid duty at her friend Sonita's wedding at home in Barbados.

13. Selena Gomez

Going for a black-tie look on your wedding day? Take inspiration from Selena Gomez's bridesmaid gown - a sleek and classy black number. The star was one of seven bridesmaids for her cousin on her big day.

14. Cara Delevingne for her sister Poppy

We love Cara in this romantic dress for her sister Poppy's wedding. Combined it with a ever-so-slightly grungey makeup look and a two-tone black and white heel, it's totally Cara.

15. Vanessa Hudgens for Ashley Tisdale

These High School Musical alums are still best pals. We love the neutral and blush tonal palette for Ashley Tisdale wedding, and Vanessa's halo braid is divine.

16. Vanessa Hudgens for Sarah Hyland

Vanessa must rock at being a bridesmaid (and a best friend) as Sarah Hyland also asked her to stand with her on her wedding day. We love her messy wave with very dainty jewellery, and natural makeup. This is the perfect example of a re-wearable bridesmaid dress.
