The right bra can either make you feel ultra-confident or desperate to free your girls the minute you arrive home. Plus, finding the right bra fit is also a mission of its own. From balconettes to strapless styles, bras are meant to support you and lift your spirits — literally and figuratively.
According to Google Trends, searches for "how to measure bust" have increased 60 percent over the last 30 days. There's also increasing evidence of the impact of breast-supporting garments on women. But while women are constantly searching for the perfect bra that offers comfort and won't dig into their shoulders, there is more to the hunt than just identifying your band and cup size.
Shop TODAY talked to bra specialists to get an accurate read of your true size and fit, along with how to determine when to ditch onerous intimates once and for all.

How to measure your bra size
Measuring your bra size is less complicated than it looks. According to bra fitting expert Zainab Akbari, all you need is a soft measuring tape to get the right fit. To begin, Akbari suggests wearing your favorite unpadded bra — no sports bras, push-up bras or minimizers — for a more accurate reading.
"Take a snug measurement around your rib cage in inches, directly under your bust and level all around," she suggests. "If you got an odd number, round up to the next whole number. Then, take a loose measurement in inches over the fullest part of your bust, keeping the tape level around your body. Ensure that the tape isn’t too tight by taking a deep breath in and out. If needed, round up to the nearest inch."
"After finding the first size, go up one band size and down one cup size so you can compare the fit," shared undergarment educator Kimmay Caldwell. For example, a 30C would move up to 32 and down to B, for a 32B. However, depending on the brand, your bra size may vary depending on the style, cut and material of the bra.
Caldwell also suggests getting fitted by a professional every time you purchase a new bra in person. She uses her own guide, which she calls "bra size starting points" to get an ideal fit.
"Size is a great starting point, and the fit is the best focus. This is why working with a trained bra fitter is so valuable," added Caldwell.

How is a bra supposed to fit?
The right bra will make you feel supported and lifted without the pain of thick wires and hooks. According to bra fitting expert Marissa Renelt, there are five specific areas that you can always check to verify if your bra is fitting correctly — your band, straps, cups, underwire and center gore (aka the space in between your breasts).

How often should I replace my bra?
There are a few things to keep in mind when you decide to replace your bra. For starters, if you feel that the underwire is starting to bend, then it's time to change your bra.
"Frayed, pilled and stretched-out fabric is a sign [you are due] for a new bra," shared Jeni Hulick, director of retention marketing at Bare Necessities.
Another thing to consider is the hook of the bra. Your bra should fit snug and be attached to the first set of hooks. "When you’re at the last, innermost set of hooks, it’s definitely time for a new bra," she added.
Hulick also recommends saying sayonara to your bra when the straps are stretched out or your body shape has changed due to weight fluctuation.
