After weeks of awards ceremonies, from the Golden Globes to the Grammys, the Oscars is one of the final nights for Hollywood's glam pack to show off their red carpet style.

Many stars played it safe last night with gorgeous neutral tones, form fitting gowns and chic cuts. Others (we're looking at you Lady Gaga) went all out for the night, embracing the closing night of the awards season with some seriously crazy designs.

As always, a few key trends showed up again and again with each dress we saw.

Here are some of the best…

1. Whitest and brightest
White and cream dresses were a huge hit last night, with Best Actress winner Julianne Moore dazzling in custom made Chanel, Reese Witherspoon going for a classically cut Tom Ford, and Lupita Nyong'o looking fab as always in Calvin Klein.

2. Beaded beauties
Heavy embellishment and beading were all over last night's red carpet. We're not sure about the colour of Emma Stone's washed out green dress, but we love the cut.  Rosemund Pike stole the show in her scarlet Givenchy number, while Jennifer Aniston looked quite the sex kitten in a plunging Versace gown.

3. Prom Queen
Giant meringue-style dresses made an unexpected comeback last night, but it wasn't always a great choice. Felicity Jones' Alexander McQueen number might have worked were it not for the unflattering silver satin, while the whole world boggled at Lady Gaga's gloves – not to mention her giant Azzedina Alaia dress. As for Jennifer Lopez, she looked undeniably fab in Elie Saab. That neckline!

But even J-Lo fell foul of her too-big dress when she tripped while walking off stage after presenting the award for Best Costume Design:

Awks!

4. Stunning and sheer
Sheer black gowns were all over the red carpet last night, but again this trend was VERY hit or miss. Margot Robbie and Lily Collins kept their looks demure with just small areas of sheer fabric. As for Rita Ora… well… if your ENTIRE ass is on show then you can probably assume your dress is a tad too sheer!
