In addition to the fact that male physical preferences are completely subjective, you need to own those perky pals of yours because excessively padded bras can be an issue for guys.
Half a cup size is generally no biggie if you’re looking for a little boost — lots of guys honestly can’t tell the difference between a large A and a small B.
Remember, training bras are intended for girls of any age who have started to get breasts and who are not yet able to be fitted with a regular bra.
If your breast size warrants a full fitting bra you should wear one, even if you are very young.
But remember that too much deceit not only sets the wrong precedent, it reveals a needless insecurity much less appealing than your beautifully smaller boobs can ever be.
