Easy to pop-in and not deal with pocket liners at all BRA SIZED BASED INSERTS: For a better, more accurate fit. For example, "34C and 44C are very different C cups" See our size chart for your best size. UNDETECTABLE: Seamless low profile grippy prevents the dreaded visible insert outline Please note these oval inserts: are not a stick on bra, significant "add a cup" inserts or push-up cleavage style inserts.
