I've been wearing the Aerie Sunny for quite a few years and it's been the best fitting and most comfortable bra I own - it's definitely my go to bra. Aerie was having their after Christmas sale with bras 50% off. I purchased a new Sunny to replace my very worn out one. Sadly this one doesn't fit. I compared the bratabase measurements I entered for the old one against the new one. The new one, the band is 3/4" shorter and stretches 2" less. The cup is 1/2" narrower with a 1/2" less depth. I had to add an extender to get it clasped and when I did I was quadding out the top and the gore was digging in. This bra is more like a 30C than 32C. I don't know if I just got a bad copy or if they changed something over the years. I will have to head back to try on some other sizes.
This bra is not owned any more

It could also be that your old one stretched in the band, especially if you wore it often.
