The 35-year-old pop star and her NFL star fiance Travis Kelce got engaged in August and the pair are reportedly in the "early stages" of planning their lavish nuptials, which are expected to take place in 2026.
A source told Us Weekly: "It's still in the very early planning stages. There is no venue or location set yet ... it is likely going to be early next year.
"She is having so much fun researching venues and locations. She's in the ideation phase and enjoying it because she's so creative.
"They don't want to have a big, over-the-top wedding with a ton of people. It will be private with friends and family, not a ton of celebrities or random people. It will be meaningful, and they will be surrounded by people who are special to them.
"Despite their celebrity, they are down-to-earth and normal. They aren't the flashy people who want a $US20 million ($A30 million) fantasy wedding. She doesn't want the pomp and circumstance. It will be more intimate."
And, Swift is already excited about choosing her dress.
The insider added: "Nearly every major designer has reached out to offer to design her wedding gown. She has been so blown away and overwhelmed and flattered at the same time, but she hasn't made a decision."
Kelce, 35, proposed with a ring he designed himself and the pair announced the engagement on Instagram.
A source previously said: "He chose it almost entirely on his own. He knows her so well and what she likes - a timeless, classic, vintage touch. He considered everything about what she'd like and want, and he paid attention to what she wears often for inspiration."
