If you want your wireless bra to serve its purpose (or any bra, for that matter), make sure you know how to look for the perfect fit. “The best way to know is to go get measured,” Antol states. “Keep in mind, all brands typically have different sizing and sizing conversions. So what size you wear at Victoria’s Secret might be different from what you wear at Aerie, Soma, or wherever!” If you’re shopping online and aren’t sure of your size, you can do a self-measurement at home with a flexible measuring tape—measuring above, below, and directly across your bust. This is more of a guideline, but if you still need a bit of help, there are a plethora of YouTube videos like this one that will walk you through it.
Because wireless bras are built differently, they may have a slightly different fit. “The fit of a wireless bra may be a bit more snug, and may feel like it’s ‘hugging’ you,’ Antol relays. She also notes that if you’re feeling smushed or spilling out anywhere (like under your armpits or around the band), the size is likely too small. In contrast, Antol notes that “if it’s too large of a size, you’ll have unfilled space between your breast tissue and the cup of the bra, also known as gaping.”
