The Ultimate Sister Sizing Bra Chart: Find Your Perfect Fit in 2025

Finding the right bra can be a challenge, especially when it comes to sister sizing. Sister sizing refers to the practice of finding a bra size that fits well by adjusting the band and cup size. For instance, if you wear a 34B, you might also fit into a 36A or a 32C. This flexibility allows you to find a more comfortable fit, especially when shopping for different styles or brands. At POIZON, we offer a curated selection of bras that cater to various sizes and preferences, ensuring you can find the perfect fit for your needs.
