Thin Knit Tops: Trying Inserts Without Overfilling

All outfit & bra guides / Fabric & silhouette
Fabric & silhouette
Thin knits follow the outline underneath them closely. Pop can add lift inside an existing bra, but the result depends on the bra, knit thickness and available space. Begin with the bra alone so you can compare the change clearly.
Check the cup and knit edges
Look for a visible cup edge, insert outline or tight area in the fabric. More padding is not automatically a smoother result. Keep each insert inside the bra cup and choose a top with enough room for the finished shape.
Check seated comfort
Sit down and reach forward in the knit top. The fabric may stretch differently across the chest in that position. If the bra feels crowded or the outline becomes more obvious, remove the inserts or try a different bra-and-top combination.

Product reference. Check the product with your own garment.

Can Pop guarantee a smooth outline under knits?
