Size & Fit Guide

This jumpsuit features a slim-fit, tailored silhouette designed to create a sleek, streamlined appearance. The fitted bodice hugs your curves elegantly, while the straight-leg pants create a long, lean line that flatters every figure. The long sleeves provide structured coverage up top, and the dramatic open-back detail adds alluring sophistication. This piece is designed to fit close to the body for a polished, custom-tailored look.

Sizing Note: This jumpsuit follows standard US/UK/EU sizing. Please measure your bust, waist, and hips carefully and compare to our size chart below for the most accurate fit.

  • Wedding Guest Sophistication: Wear with elegant heeled sandals or pumps, a chic clutch, statement earrings, minimal necklace (or skip it to highlight the back), and polished hair in a low chignon or Hollywood waves for weddings, rehearsal dinners, or formal celebrations where you want to look stunning without upstaging the bride

Styling Q&A

Q: How long does shipping take?
A: This item qualifies for standard delivery and typically arrives in 7-12 business days within the USA.
Q: What should I wear underneath this jumpsuit with the open back?
A: For the open-back design, skip the traditional bra and opt for stick-on cups, adhesive bras, breast petals, or a backless/low-back bra with clear straps if you need support. Seamless nude underwear works best to avoid visible lines. The key is ensuring nothing shows from behind.
Q: How do I know if this will fit my torso length?
A: Jumpsuits can be tricky for torso length. If you typically find one-pieces too short in the torso, size up. You can always have a tailor adjust the leg length if needed, but torso length is harder to alter. The crotch should sit comfortably without pulling.
Q: Is the open back too revealing for a wedding?
A: It depends on the wedding's formality and setting. For most modern weddings, this is elegant and appropriate—the long sleeves and straight-leg pants balance the open back beautifully. For very traditional or religious ceremonies, you might want something more conservative. When in doubt, ask the couple or skip it for the ceremony and wear it to the reception or rehearsal dinner.
Q: What heel height works best with straight-leg pants?
A: Straight-leg jumpsuits look stunning with heels of any height—from kitten heels to sky-high stilettos. The key is that the hem should just skim the floor when wearing your chosen heel height. If you're petite, higher heels create a more elongated look. Taller women can wear lower heels or platforms.
Q: How can I style my hair to show off the open back?
A: An updo, high ponytail, side-swept style, or slicked-back bun showcases the open-back beautifully. If you prefer hair down, consider a side part with hair swept over one shoulder, or loose waves pulled slightly forward. The goal is to keep your back visible so the dramatic detail isn't hidden.
Q: Can I wear this in cooler weather or just warm weather?
A: While the open back is perfect for spring/summer, you can absolutely wear this year-round for indoor events. Layer an elegant coat, faux fur stole, or wrap for travel to and from the venue. The long sleeves actually provide more warmth than sleeveless options.
Q: What if the pants are too long for my height?
A: Straight-leg pants are easy to hem! Any tailor can adjust the length for a perfect fit. Bring the shoes you plan to wear to your tailoring appointment so they can hem it to the exact right length for your heel height.
