The August Sky Women’s Square Neck U-Neck Midi Dress brings effortless versatility to your wardrobe with its innovative dual-neckline design. Wear the structured square neckline for a polished daytime look, or flip to the softer U-neck for evening elegance — all in one garment.
We crafted this midi silhouette to hit just below the knee, creating a universally flattering length that works from the office to weekend brunch.

What the numbers mean
We chose a premium stretch-blend fabric that moves with you through every activity while maintaining its structure throughout the day. The 68% polyester base provides durability and wrinkle resistance, while 28% rayon adds a soft hand feel and natural drape. A 4% spandex content ensures the bodice hugs your curves comfortably without feeling restrictive.
The dress construction features French seams throughout the bodice for a clean interior finish, and the skirt includes a full opaque lining so you never have to worry about transparency. Our hidden back zipper sits flat against the body and extends approximately 16 inches from the neckline, making the dress easy to slip on and off while maintaining smooth, uninterrupted lines when worn.
The August Sky square neck midi dress runs true to standard US sizing, with the bodice designed to fit close through the bust and waist before releasing into the A-line skirt. We recommend ordering your usual dress size for the intended fitted-bodice look.
For reference, our size Medium fits a 36-inch bust, 29-inch waist, and 39-inch hip measurement. The stretch content in the fabric accommodates approximately one inch of variance in each direction. If you typically size between measurements or prefer a looser fit through the bodice, we suggest sizing up — the defined waist seam will still create shape even with extra room. The midi length is designed for heights between 5’4″ and 5’8″; taller frames may find the hem hits closer to mid-calf, while petite frames may see it fall slightly longer past the knee.
The dual-neckline design transforms this piece from professional to casual with a simple adjustment. Wear the square neckline forward with structured blazers and classic pumps for office meetings, then flip to the softer U-neck with strappy sandals and statement earrings for dinner plans.
We see customers layering lightweight cardigans over the square-neck version during cooler months, while the U-neck pairs beautifully with delicate pendant necklaces that sit inside the neckline. The midi length works year-round — bare legs and ballet flats in summer, opaque tights and ankle boots when temperatures drop. Many shoppers also appreciate how well the dress travels, since the wrinkle-resistant fabric holds up in luggage and the reversible styling essentially gives you two outfits in one garment. This adaptability makes it a frequent choice for our customers building capsule wardrobes or shopping for casual dresses that transition seamlessly between different dress codes.
Care instructions & longevity
Washing & drying
Machine wash the dress in cold water on a gentle cycle, and turn it inside-out to protect the exterior fabric from friction. We recommend using a mesh laundry bag to prevent the zipper from snagging other items in the load. Skip the dryer entirely — the polyester-rayon blend air-dries quickly when hung on a padded hanger or laid flat on a drying rack, and avoiding heat helps maintain the fabric’s stretch recovery and prevents shrinkage in the rayon fibers.
Storage & maintenance
Hang the dress on a padded or wide hanger to prevent shoulder dimples, and store it away from direct sunlight to preserve the color. If wrinkles develop during storage, a quick steam or cool iron on the reverse side smooths the fabric without damaging the stretch content. With proper care, the dress maintains its shape and color vibrancy through dozens of wears and washes.

What the crews say
Common questions about the August Sky square neck midi dress
The August Sky women’s square neck U-neck midi dress features a reversible neckline construction. Simply slip the dress over your head with your preferred neckline facing forward. The back neckline sits comfortably against your skin and remains hidden under your hair or accessories. No special adjustments or ties are required — the design is intuitive and takes seconds to switch.
The square neckline sits slightly wider than a standard bra strap placement, so we recommend wearing a strapless bra, adhesive cups, or a bra with clear removable straps when wearing that neckline forward. The U-neck version accommodates regular bra straps more easily, though many customers still prefer strapless options for a cleaner look. The bodice includes light structure so additional support is optional depending on your personal preference.
The square neckline creates a bold horizontal line that pairs beautifully with drop earrings or statement earrings, while keeping necklaces minimal or skipping them entirely to let the neckline shine. For the U-neck version, delicate pendant necklaces that sit inside the neckline work perfectly. Belt the waist with a thin or medium-width belt to emphasize the defined waist seam, or leave it unbelted for a streamlined silhouette. Structured handbags complement the square neck’s tailored look, while softer crossbody bags suit the U-neck styling.
The polyester-dominant fabric blend resists wrinkling significantly better than natural fibers like cotton or linen. You may see minor creasing behind the knees after sitting for extended periods, but these smooth out quickly once you stand and move. The dress maintains a polished appearance throughout a full day of wear without needing mid-day touch-ups. For travel, rolling the dress instead of folding it further minimizes any crease formation.
The dress works well for semi-formal occasions like cocktail parties, daytime weddings, and upscale dinners, especially when styled with heels and elegant accessories. For black-tie or very formal events, you may want a longer gown or more structured formal wear. The midi length and versatile neckline options make this piece ideal for events with business-formal or cocktail attire dress codes, and many customers wear it to celebrations where they want to look polished without appearing overly dressy.
This dress follows the same sizing chart as our other fitted-bodice styles, so if you own another August Sky dress with a defined waist, order the same size. The bodice fit is slightly more structured than our wrap or flowy styles due to the tailored seaming. If you typically wear our relaxed-fit dresses and are unsure, we recommend referencing the specific bust and waist measurements on our size chart rather than going by your usual letter size across all dress styles.
Yes, a local tailor can hem the dress to your preferred length. Because the skirt is lined, the alteration involves shortening both the outer fabric and the lining, which most tailors handle routinely. Keep in mind that shortening the dress will slightly alter the proportions of the A-line silhouette, so we recommend trying the dress on and pinning your desired length before taking it to a tailor. Many petite customers have the hem taken up two to three inches and are very happy with the results.
