Is It Normal for Bras to Feel Different Even in the Same Size?

I’ve noticed that even when I buy bras in the same size, they don’t always fit the same — some feel perfect, while others have issues like slight gaping, tighter bands, or straps that need constant adjusting.

Is this just because of different styles and designs, or does it mean the size isn’t actually right?

I’m also confused about how much variation is “normal.” Like, should every bra in your correct size fit almost perfectly, or is some inconsistency expected depending on the brand or type?

Would love to hear how you all deal with this — do you stick to one style that works, or adjust sizes depending on the bra?
