A party dress is typically a semi-formal option you can wear to events like weddings, cocktail parties, or other special occasions. You’ll usually find party dresses designed with elevated fabrics, including chiffon, silk, and lace. Boutique party dresses are also generally knee-length or shorter to exude an energetic and sassy vibe.

If you’re heading to a semi-formal event during the cooler months and want to layer up, it can be tough to figure out which outerwear matches the aesthetic and energy of your boutique party dress. Here are a few recommendations from our style experts to guide and inspire you:

These options explore a variety of lengths and materials to ensure you find something that matches the weather and your personal boutique cocktail dress style!

While many people use the two terms interchangeably, there is a subtle difference between boutique party dresses and cocktail dresses. 

A cocktail dress is slightly more formal than a party dress and is usually the right choice for galas, charity events, and weddings. They may be made of higher-end fabrics, feature sophisticated silhouettes, and have a slightly longer hemline.

A semi-formal or formal maxi dress is usually called a gown, and they’re not the best option for a cocktail party. These full-length styles are too formal and are best suited to black-tie events.

There are some semi-casual maxi dresses that may be appropriate for less formal events, but you need to accessorize them correctly. We recommend wearing a matching jewelry set and a pair of chic slingback shoes to achieve the cocktail attire dress code.

If you’re wondering which boutique party dresses are the best for cocktail parties, we say you should go for a midi or a mini dress. There is such a thing as going too formal, and a sweeping gown just isn’t the right choice.

Explore boutique cocktail dresses that feature unusual necklines or unique patterns to spice up your look and express yourself in a fun, flirty way. Compliment your dress with simple pumps in either classic black, neutral nude, or a color that matches your dress. We would skip the purse and choose a small clutch that fits just your phone and other essentials.
