Product Insights
Knix's Black Sculpting Tie Balconette offers wireless support up to a G cup with 42% elastane for a soft, hugging sculpt, adjustable front tie for neckline depth, and a sale price of $39.95 CAD undercutting Spanx, but it is designed only for lounging and light swimming, with UPF 50+ protection that applies solely to dry, unstretched fabric and decreases when stretched, and requires rinsing after water exposure to preserve elastic.
Verified claims
- Care and UV
- UPF 50+ protection decreases when wet or stretched; rinse in fresh water after chlorine or salt water exposure to preserve fabric and elastic.
- Support
- Wireless balconette supports up to a G cup with 42% elastane for casual wear.
- Brand availability
- Knix is a Canadian brand sold at Simons for local purchase.
- Neckline
- Front tie adjusts neckline depth and coverage for a customizable look.
- Fit
- Provides wireless support up to a G cup, and the front tie allows adjustable coverage for larger busts.
- Swim activity level
- Adjustable ties provide moderate support for light swimming and lounging.
- Price advantage
- Sale price $39.95 CAD undercuts Spanx's $80 USD halter, and Canadian shoppers can potentially avoid cross-border duties.
- UPF wet performance
- UPF 50+ rating applies only to dry, unstretched fabric.
- Material
- Body: 58% nylon, 42% LYCRA; Lining: 85% nylon, 15% spandex – triple the elastane of typical shapewear for a soft, hugging sculpt.
- Value
- Knix's 42% LYCRA® elastane body fabric gives a softer, everyday sculpt than Spanx's 15% elastane shell at a lower price.
- Use case
- Designed for lounging and light swimming, not for laps or high-impact activity.
- Chlorine care
- Rinse in fresh water after chlorine or salt water exposure, machine wash cold, do not bleach or iron, and lay flat to dry.
- Sculpt level
- The double-layer Premium Sculpt fabric provides light, everyday smoothing rather than full compression control.

A swim top for a smoothed, shaped silhouette
This balconette swim top is made with double-layer Premium Sculpt fabric that's described as smoothing the body, slightly hugging it, and shaping natural curves. It's a fit for swimmers who want a top with light sculpting rather than just basic coverage. Note that these smoothing and shaping effects come from the product description, not reported customer experiences.[2,3]
A wireless swim top for a natural bust shape
This Knix balconette swim top uses soft wireless, unpadded cups meant to give a natural shape, with string ties in front that you can adjust for fit. Per the product copy, the wireless design is offered in sizes up to G cup.[1,3]
Sun-protected swimming and beach days
This Knix balconette swim top is made with UPF 50+ fabric for sun protection while you swim, lounge, or spend time outdoors. A matching swim bottom is available and sold separately if you want to complete the set.[3]
Dial in your neckline and strap fit at the beach or pool
This balconette swim top is made for customizing how it sits on you. The tie-front detail lets you adjust the neckline to your liking, and the shoulder straps each have an adjustable slider so you can fine-tune the fit through the torso. It suits swimmers who want a top they can tweak for different levels of coverage or comfort.[1,4]
