You'd better buy a soft ruler and measure it first, because wearing the wrong bra size is not as obvious as wearing the wrong shoes. Maybe you don't even know that the two cups are smaller, and the seller even said to you, "Look, there is a gap, just like in the advertisement (most of the advertisements are underwear, which gives people a tempting feeling, but they are all small)". Sellers are never responsible for the health of our consumers, but you should know that wearing underwear is much more likely to get breast cancer because it compresses breasts and axillary lymph. Go to the underwear store and ask for 70B, 70C directly. Try it in the fitting room yourself. You can't press the cup (it's hard to connect without pressing the cup, so you have to accept this reality), and you can't empty the cup.
Only 32, 34, those without cups written on them are unqualified underwear. I bought it in junior high school. The size of the cup is larger than a and smaller than b, and they are all sponges. The sponges in China's underwear are all made of petroleum residues, no matter what famous brands or brands, they are sponges. Wearing too much will not only make your breasts bigger, your arms thicker, your abdomen bulge, and your baby will have no milk, but also make your nipples and areola darker and darker, because the sponge is full of toxins. Wear it all year round, and finally breast cancer is waiting for you.
I know that underwear is expensive, and the best underwear is around 200 yuan. You can only wear it 1 year at most. But health is more important. So I suggest you don't be reluctant to spend money. In the end, it was not only myself but also my family who cried.
