Reddit mentions of Mary-Kate And Ashley - Two - Perfume for Women - Juicy Peach Freesia - Eau De Toilette Spray - 1.0 Oz / 30 Ml

Apparently you aren't the only one looking for discontinued MK&A fragrances! So Two isn't listed on Fragrantica but one is. One is a combo of pear and freesia. According to this perfume listing on Amazon, Two is a combination of peach and freesia, so there's a single note difference. So you could start by searching for One.

This Jo Malone fragrance is English pear + freesia, just like One.

This Love2Love EDT has rose and peach in it. There's also a variety in purple packaging that has freesia in it, but that one seems to be more woody-spicy-floral than the fruity floral you're looking for. The Love2love perfumes are found in drugstores and big box stores like Kmart/Walmart.

This perfume by Callio fragrance seems like a good bet. It's got cantaloupe, freesia, and peach.

This perfume is a flanker to the Halloween line by Jesus de Pozo and has freesia, peach, and pear along with other notes. The Halloween fragrances are sometimes found at TJMaxx and the like, but if you're looking for a specific flanker like this, ebay might be easier.

The Demeter line does single note fragrances, including a peach and a freesia. You could try buying one of each and using them together to see if it comes close.

The unfortunate thing is that when companies list notes, they don't always give the full notes profile (so there might be an underlying spiciness that isn't listed, for example), and perfumes are made from synthetics so what smells like peach to one person could smell like oranges or feet to someone else.
