How many times have you purchased a dress and just left it hanging in your closet because you didn’t know what undergarments to pair with it? This holiday season we want you flaunt those outfits or maybe even try something new. Scroll down to see our smart solutions for six problematic clothing situations. 1. THE DEEP-PLUNGE BODYSUIT When your top has a low-cut neckline, it’s important to wear supportive undergarments, but the most supportive ones also tend to have the most fabric up top. Enter Va Bien: It offers one of the best deep-plunge shapers we’ve seen. The straps are adjustable and convertible, and it comes in sizes up to an E cup 2. THE FLESH-TONED SHORT Cutouts are trending at the moment. Not only are they cute, but they allow you to show as much (or as little) skin as you’d like. But what can you wear underneath that won’t interfere with the peekaboo designs? Flesh-toned shorts are the answer. These lifesavers from Spanx come in four shades that match a range of skin tones (plus two sparkling neutral hues and basic black). 3. THE HALTER SHAPER Finding the perfect halter shaper can be a challenge. And finding one that actually works is even harder. This pretty onesie boasts adjustable halter straps as well as a thong. Layer under a dress with an asymmetrical hem like this one by StyleStalker and you have a winning combo. 4. THE MULTI-WAY DRESS A smoothing slip is essential for a sleek look, and this piece by Maidenform has removable straps that can be worn multiple ways to accommodate a variety of dress styles. Wearing the slip with one strap over your shoulder works beautifully with this lacy sheath by Thalia Sodi. 5. THE CLASSIC BODYSUIT If your dress is sheer, you’ll want a foundation piece that offers full coverage. And if you choose a super-sexy number like this one by Forever 21, the undergarments shouldn’t compete with the dress or make it look gaudy. Wacoal’s bodysuit is perfect for this look because it’s unobtrusive, it’s comfortable, and it smooths your curves. 6. THE MULTI-WAY BODYSUIT Pieces with intricate necklines call for shapers that can be adjusted in multiple ways. Take this bodysuit by Wolford, which can be layered under the most complicated designs. To make it work under this cute one-shoulder dress, remove the right strap, leaving the left one attached. Cross the left strap over your right shoulder, attach it to the connector behind the right shoulder, and voilà—you’re ready to steal the spotlight.
