The Bumbas Boost Inserts work best with tight fitted, structured, tops and swimsuits.
They are not designed for loose fitted clothing, such as t-shirts.
We suggest you choose the size closest to your current bra size.
If you are in between sizes, size up for a more dramatic lift or size down for a more subtle lift.
