How do you know if your bra cup size is too small?
It’s more common for women to be wearing a cup size that’s too small than too big. An obvious sign that the cups are too small is if the underwire presses in at the sides of the breasts or if you have red marks on your breasts when you take your bra off in the evening.
How tight should the band on a bra be?
A level band.
“The band should be level all the way around, firm and secure but not too tight or too loose. The gore (the part in the middle between the cups), in a wired bra, should sit flat against your sternum. It should not bow out or press in.”
How do you know if your bra cup is too big?
There’s a gap at the top of the cups.
When you look down at your bra do you notice space between your breasts and the cup? If so, it’s too big. If you aren’t able to see any gaps while standing up, try leaning over while looking into a mirror. If there is extra space in your cups it’s time for a new size.
Does band size affect cup size?
Proper cup fit is influenced by band size. As the band size changes, so does the cup size. For every band size you go down, you should go up one cup. If you are in a 34D with a good cup fit, but want to go down to a 32 band, you would go to a 32DD for a tighter band with the same cup fit.
Which type of bra should wear for heavy breast?
An underwired bra is also recommended as the underwire offers very good support and helps to lift the bust. The underwire spreads the weight and distributes it to the sides of the bra. The higher up the side and between the bust that the underwire goes the bigger the area over which it spreads the support.
What hook are you supposed to wear your bra on?
loosest hook
You should always fasten your new bra on the loosest hook.

Where should the underwire of a bra sit?
Your bra’s underwire should sit flat against your chest and around the contour of your breast without digging in or gaping. No part of your breast tissue should sit under or between the wire compartments. The underwire is a vital component of your bra’s ability to lift and support, particularly for fuller cup sized.
