10 Signs You’re Wearing A Wrong Bra Size
5: Jutting — The bra should not be jutting out; it should be firmly placed on your breast and cover it nicely without any parts sticking out. If you experience any kind of areas jutting out, then you need a better fitting bra.
6: Grooves — If you experience any form of grooves when wearing the bra, it means that you need to check back on the size. Choose a smaller band or cups until you get the perfect flattering fit you are after.
7: Sagging Breasts — Your bra is supposed to support your breast and hide any form of sagging. If you have gotten yourself a well fitted bra, it can actually camouflage any form of sagging you may experience and makes it look firm and contoured.
8: Poking Wires — Feeling the sensation of poking wires against your skin? This is one tell tale sign that your bra is too big for you. If the cups are too big, the wire would tend to move around instead of being placed firmly to support the breasts.
9: Straps Leaving Marks — If the straps of your bra are leaving red marks then it is possible that the bra is just too small or too tight to fit you. You need to lengthen those straps by adjusting it or you need get a new bra that would fit you better.
10: Discomfort — This is the biggest indicator of an ill-fitting bra. A bra that fit you well would flatter your shape and leaves you feeling comfortable. Any sign of discomfort is a sure fire indicator of a wrongly fitted bra.
