Tips For Choosing The Right Formal Dress Silhouette For Your Body Type
When choosing a formal gown or dress, it's important to choose a silhouette that flatters your body type. A dress that fits well and accentuates your best features will make you feel confident and beautiful. Here are some tips for choosing the right silhouette for your body type:
- If you have an hourglass figure, opt for a dress with a fitted bodice and a flowing skirt to accentuate your curves.
- If you have a pear-shaped figure, opt for a dress with a fitted bodice and a full skirt to balance out your proportions.
- If you have a rectangle-shaped figure, opt for a dress with a defined waistline and a flowing skirt to create the illusion of curves.
- If you have an apple-shaped figure, opt for a dress with a v-neckline and an empire waist to draw attention to your upper body.
No matter what your body type, there is a formal dress or gown out there that will flatter your figure and make you feel confident and beautiful.
What is the difference between a formal dress and a semi-formal dress?
There are subtle differences between formal and semi-formal dresses. When shopping for the right dressy attire, consider how you will style your look for the dress code of the event you're attending and the vibe of the venue location. Formal attire can also be called a black-tie dress code that lends itself to the most glamorous attire. Explore specialty gowns designed with accents that elevate your formal dress with hand-beading, rhinestone embellishments, or detailed embroidery. Expect to see this dress code for weddings, galas, and proms—these events usually require a floor-length dress with an A-line or mermaid silhouette, ball gown dresses, or a formal dress with luxe details like rhinestones or lace. A semi-formal dress for homecoming, weddings, or anniversary parties can come in shorter or midi lengths, two-piece styles, or a classic party length. Choose formal midi dresses that feature glam detailing like sequin bodices or high-slit satin skirts as this length offers more variety in semi-formal silhouettes. Explore necklines on formal dresses to highlight jewelry from plunge, cowl, and scoop necks to sweetheart or V-necklines. Strapless, spaghetti straps, and off-the-shoulder formal styles are sexy gown details to adore on both formal gowns and semi-formal dresses. The type of event you're attending, a military ball versus a Broadway show or a wedding at an upscale hotel versus one at the local house of worship, can also be a good clue to tell you if a formal dress code or semi-formal dress code is required.
Are formal dresses long?
No, not all formal dresses are long. Formal dresses are traditionally long in length and feature beautiful, eye-catching details like rhinestones, pleats, lace, and embroidery. The special occasion dress collections at Windsor feature a glamorous variety of short, midi, and long dress lengths to accommodate every occasion. When it comes to silhouettes, discover stunning long silhouettes like A-line, mermaid, trumpet, and sheath dresses to stay on-trend. Formal short dresses can be found in midi-lengths or shorter styles like party or skater dresses but come in elevated designs showcasing sleeves, necklines, and of course luxe fabrications from velvet to satin, sequin to rhinestone. These days you can expect to see high-low satin dresses or unique two-piece dresses as floor-length alternatives for trendsetters looking to revamp their formal dress assortment.
