To convert a vintage bra to a modern size, measure your chest right below your breasts and the fullest part of your breasts. How much larger your breasts are than your chest determines your vintage bra size. You are an A cup if your breasts are up to 1 inch larger than your chest, a B cup if they are 2 inches larger, and so on.Continue Reading
Another way of calculating vintage bra size is by using the “plus four” method, which involves adding 4 inches to the band measurement of your modern bra size to find your vintage band size. You then subtract 4 inches from your modern band size to calculate your vintage cup size. Vintage bras typically have larger bands and smaller cups than modern bras.
It is also worth keeping in mind that even if you do the conversion correctly, vintage bras are usually less supportive than modern bras, because vintage bras rarely have underwires. The bullet bra offers the most support. The cups on vintage bras are also usually higher than those of modern bras, so it's a good idea to purchase a vintage bra with adjustable straps so that you can tailor the fit for your body.Learn more about Clothing
