Document Description Plus

The NS173 is a Colombian waist trainer vest that does what a standard waist cincher cannot, it covers the full torso from just below the bust all the way around the back, smoothing the upper and lower back for a clean, seamless silhouette under any outfit.

Six steel bones, two at the front, two at the back, and one on each side, keep the vest completely rigid so it never folds, rolls, or loses its shape through a full day of wear. Ultra-Sculpt Powernet compression defines the waist and encourages upright posture. Three rows of hooks give you precise fit adjustment. Thin straps at the front and a thicker back panel keep the vest sitting flat and supported on your shoulders. Latex free. Made in Colombia.

    Built for real days

    The NS173 is built for women who want more than waist definition. The vest cut covers the full torso including the upper back, which means no bra lines, no back bulges, and no rolling fabric showing through fitted clothing. Everything from just below the bust to the hips looks smooth and flat.

    Six steel bones spread across the front, back, and sides make the NS173 the most structured garment in the collection. It holds its shape through a full day of sitting, standing, and moving without ever needing to be readjusted. The thicker back panel adds coverage and stability without restricting movement.

    A few things that make wearing the NS173 easier every day:

    • Hook from the bottom up, one hook at a time, pulling the fabric slightly inward with each hook for a clean compression line.
    • Start on the middle hook setting and tighten after the first hour once your body settles in.
    • Smooth the back panel flat after hooking up to make sure all six steel bones are sitting evenly around your torso.
    • If you are between sizes, size up. Ultra-Sculpt compression is firm and a size too small will feel restrictive across the back and shoulders.
    How to wear

    Step 1 — Wrap the NS173 around your torso, positioning the back panel flat across your upper and lower back before hooking the front.

    Step 2 — Hook the front closure from the bottom up, one hook at a time. Pull the fabric slightly inward with each hook for a clean compression line across the abdomen.

    Step 3 — Start on the middle hook setting. You can tighten to the inner hooks after the first hour once your body settles in.

    Step 4 — Adjust the straps so the vest sits flat on your shoulders with no pulling at the front neckline or bunching at the back.

    Step 5 — Smooth the back panel from the shoulders downward to make sure all the steel bones are sitting flat and evenly before getting dressed.

    Frequently asked questions

    Does the NS173 cover the upper back?

    Yes. The NS173 is a full vest that covers the entire torso including the upper and lower back. It smooths bra lines, back bulges, and any fabric rolling that shows through fitted tops and dresses. This is the key difference between the NS173 and a standard waist cincher which only covers the waist.

    What is the difference between the NS173 and the NS006?

    Both are Ultra-Sculpt Powernet waist trainers with three hook rows and steel bones. The NS006 is a waist cincher that covers the waist only with removable straps. The NS173 is a full vest that extends up the torso and covers the full back, smoothing bra lines and back bulges. Choose the NS006 for waist-only focus and versatility under different necklines. Choose the NS173 for full torso coverage and back smoothing.

    Is the NS173 latex free?

    Yes. The NS173 is made entirely of Powernet, a latex-free fabric. It delivers firm Ultra-Sculpt compression without latex, making it a comfortable alternative for women with latex sensitivity or anyone who prefers a non-latex waist trainer.

    What size should I order in the NS173?

    Use your waist and bust measurements together since the NS173 covers the full torso. If you are between sizes, size up. Ultra-Sculpt compression is firm and a size too small will feel restrictive across the back and shoulders as well as the waist. Our waist trainer size guide walks you through exactly how to measure.

    Does the NS173 help with posture?

    Yes. Six steel bones spread across the front, back, and sides keep your torso upright and discourage slouching while you wear it. The full back coverage adds additional structure that a waist-only cincher cannot provide. Many customers wear the NS173 specifically for the posture support it provides during long desk days or time on their feet.
