Part of being invited to a wedding means you have to find the perfect dress for the occasion. For women looking for a petite cocktail dress, this is often easier said than done. Petite dresses aren't always easy to come by and the in-store selection usually isn't that great. But the right dress is worth the search for a great, comfortable fit that doesn't require alterations.

When the wedding you're going to call requires semi-formal attire, a cocktail dress is a good go-to option. Cocktail dresses are defined as a dress that typically falls right above or below the knee, so it's usually on the shorter side. For petite people, finding this length can be difficult because a regular length can sometimes run too long and ends up needing to be hemmed. It's nice to be able to find a cocktail dress that fits just right without spending extra money on alterations.

We've searched the internet for the best petite cocktail dresses, some of which are versatile enough to be worn to a variety of different weddings, and some of which feel more trendy and modern. Here are our favorites.

FAQ
  • Do cocktail dresses have to be short?

    Traditionally, a cocktail dress is a shorter dress, something that hits at or just above the knee. This is because the shorter length makes them appear more casual and less formal. However, there are no strict rules: in some cases, a midi or maxi dress can be appropriate as cocktail attire as well.

  • Can cocktail dresses be casual?

    With the right accessories, a more casual dress can easily be worn as cocktail party and wedding attire. These more casual dresses are usually also more versatile.

  • Should you avoid white cocktail dresses at a wedding?

    Generally speaking, the one fashion rule most people seem to continue to follow at a wedding is to avoid wearing white unless you're the bride. Even if your cocktail dress is casual, your best bet is to opt for any other color aside from white.
