9. The Wires Feel Like They’re Poking You
If you can feel the underwire of your bra poking you and moving around, your bra is definitely too big. A proper fitted bra will sit firmly against your body, therefore not allowing the underwire to move around.
10. It Doesn’t Feel Comfortable
If you go all day long adjusting your bra and if you feel uncomfortable in it all hours of the day, it’s definitely not the right size. It could be too big, or too small, but when a bra properly fits your breasts and your body, you will hardly even notice that you’re wearing it. Give your bra a few days to break in, however. The elastic in your band is quite new and will eventually stretch to fit you, but you need to give it a little bit of time.
One of the best pieces of advice I can give is to get a proper bra fitting at a reputable department store, like Nordstrom. You will be surprised at their wealth of knowledge and how quickly they can get you into your “real” size!
