Extension materials for chest patches and invisible underwear

Matters needing attention
1. It is best not to wear a pure silicone invisible bra for MM with a C-cup or above
Silicone mainly has a plump effect, and larger breasts no longer require a fuller effect. The more important reason is that pure silicone is heavier than fabric bras, and wearing it will put a greater burden on larger breasts.
2. MM with severe sagging should not use an invisible bra
Invisible bras have basically no good solution for severely sagging MM unless revolutionary products are developed.
3. Invisible bras cannot improve chest shape
Invisible bras cannot correct the shape of the chest. They are not body shaping underwear, but their gathering effect is still good, making them useful for external expansion.
