What makes the Sweater Slip different from a normal undershirt?

The sweater slip is special in both appearance and purpose. Our sweater slips are made of a tricot 4-way breathable, ultra-thin fabric, which makes it easy for sweaters to flow over the top and maintain the desired appearance.

The seams are minuscule and undetectable as they're created with a single-stretch lingerie stitch and raglan sleeve.

Is The Sweater Slip patented?

We currently have a provisional patent and the utility patent is pending.

Owner and founder Julie Oliver loves sweater season but almost all sweaters irritate her skin. Over the years she tried shapewear or layering t-shirts to alleviate this problem.  Only to be disappointed. These garments cling to your sweater, they are bulky and loose the shape and style of your sweater and female silhouette and ultimately don't stop the irritation.
