A thin strap bra is a staple under many sleeveless dresses and tops. It’s important to find a bra that fits well and is comfortable over time. Choosing one with a supportive band and wire structure will help maintain shape, while a strapless design helps provide coverage without the need for a garter belt.
The band provides 80 percent of a bra’s support, so it’s especially crucial to fit it properly. A good test is to hop up and down a few times while wearing your new bra. If your breasts start to spill out of their cups, it’s likely that your band is a size too big. A quick fix is to cinch the band with a safety pin to keep it from riding up, but be careful not to cinch it so tight that you can’t breathe or get red indentations on your neck and shoulders.
If you’re unsure about your band size, try using a piece of string to measure yourself. Stand up straight and wrap the string around your back and under your bust, ensuring that it’s an even, level line across your body. Then, subtract your band measurement from your bust measurement and match that number to a bra chart to figure out your cup size.
For example, a 34B minus 29 equals an A cup, so you’d want to select an A-cup bra. Keep in mind that every inch of difference you make between your band and cup sizes represents a one-size increase or decrease in a bra.
