When it comes to cups, Cohen suggests aiming for “comfortably full.” “You don't want your breasts to spill out of the cup of the bra, whereas too much room can create empty, unsupported space. Look down to ensure the breast tissue fits evenly in both cups with no overflow and no gaping.
The band of the bra should be straight and level. It shouldn't ride up. The straps should always stay in place without digging or falling. Your breasts should fill the cups without over-spilling.
THE BRA BAND
You should feel it holding, but it should not be so tight that it is uncomfortable. As a guideline, you should be able to comfortably run two fingers under both sides of the bra at the same time. If the bra pulls away from your body easily, it is too loose.
If you are someone who suffers from gapping at the centre front of the bra then your cups are too small and consider sizing up. The fabric between the cups needs to sit flush against your sternum with a traditional everyday bra design.
The underwire must sit against the chest exactly where the breast flesh finishes. Make sure the sides of the bra are not too high under the arms and the centre is not being significantly pulled away from your chest. It is vital to check both underwires as some will have one side fuller than the other.
A bra that is too tight can easily cause skin abrasions and chafing from the constant rubbing against your skin. You may see red lines anywhere the bra falls, including your overbust, underbust, back, or shoulders.
This is actually very normal. You're wearing a new size and your bra is new so it's going to feel the most snug at the beginning, that's ok, that means it's fitting.
If your bra's center panel is not resting on your sternum, this could be a sign that your cup size is too small. If the underwires are pointing outward and away from your body, this too is a sign that your cup size could be too small. The band of the bra should be parallel to the floor.
If the centre panel of your bra gapes and does not lie flat then your bra cup may be too small and band size too big. Our bra specialists advise – “Try increasing the bra cup size and reducing the bra band size. Also try a stretchy fabric on the bra.”
The number one rule in bra sizing is that the center gore — the small strip of fabric between the cups — of the bra should always lay flat against your chest. If it's not doing that, one of two things could be happening. One is that, you guessed it, it doesn't fit right.
Typically, if you have gaping bra cups, your breasts are resting at the bottom of the cups. To fix this, start by tightening the bra straps, ensuring your band stays straight across your back. If your cups fit well but there is still a gap at the top, consider going down a cup size or choosing a different style of bra.
Even with gentle usage and care, all bras will lose their shape over time as the elastic fibres in the band and straps begins to deteriorate. It's generally recommended that a bra should last anywhere between 6-9 months, although we think that with good care your bras should last a lot longer.
No matter the type of bra, the band should fit comfortably around your body, snug but not tight.
One of the most common reasons for breast pain is wearing a bra that doesn't fit well. Many women wear a bra that is the wrong size. Wearing a bra that fits you well and has good support can help lessen and prevent breast pain.
If there are gaps between the cup and your breast, you're wearing a cup size too big. If you find your breast spilling over the top, side, or bottom of the cup, you most likely need to go up in size. You also need to consider a larger cup size if the underwire or bottom of the bra is resting on your breasts.
There's nothing wrong with wearing a bra while you sleep if that's what you're comfortable with. Sleeping in a bra will not make a girl's breasts perkier or prevent them from getting saggy. And it will not stop breasts from growing or cause breast cancer.

It's also important to rotate your bras, so the cups and straps can relax. This allows them to retain their shape and elasticity. “You can wear the same bra two days in a row, as long as you take it off for several hours in between to allow the bra to relax,” Dr. Vij says.
You should wash your bra after 2 or 3 wears, or once every 1 or 2 weeks if you're not wearing it every day. Wash your jeans as rarely as possible, unless you're going for the distressed look. Wash sweaters as often as needed, but be careful not to stretch or shrink them as they dry.
“There hasn't been any scientific evidence that not wearing a bra has any long-lasting effects, but we do know that skin can begin to sag over time with gravity and other natural effects, supporting 'the girls' is an important part of preserving lift and elasticity in the skin tissue,” CEO of breast-inclusive bra ...
BRA PROBLEM - WHY DO bras BULGE AT THE SIDES? If you have unwanted bra bulge at the sides it could be the bra band is too narrow. Alternatively the bra band size could be too small or the bra cup size is too small.
There could be a number of reasons your bra doesn't feel comfortable. It could be due to a poor fit or it could be a cheaply made bra.

Is it Normal For Bras to Leave Marks? Whilst bras leaving red marks on the side is actually quite a common problem (around 80% of women are wearing the wrong bra size), it's not necessarily normal if the bra fits properly and you've worn it for long enough.
Blake says wearing a bra doesn't prevent your breasts from sagging and not wearing one doesn't cause your breasts to sag. “Wearing a bra doesn't affect the risk of breast sagging, or what is called 'breast ptosis,'” she says. It also won't impact the shape of your breasts.
