Across the board, the most romantic gestures are those that are specific to the girl you're trying to woo. We thrive on knowing that better than anyone else, we know you best, and you know us. Spouses,boyfriends, significant others, lovers - they're meant to be our best friends but on a whole different level. So romance becomes a mix between "knowledge of another person" and being "generous". It's those thoughtful gifts which tell the person, "Hey, I was listening, I know you." And in most cases, it takes a bit of work. It requires hearing what is being said, taking mental notes, and really getting to know each other. So when she casually says, "I love green M&Ms!" and picks them all out of the bag, play off of that. Choose something she loves and put a spin on it. That's what makes it personal and thus a "romantic" gesture.
"If he can cook or prepare that day's meal; preferably dinner, but lunch can work too. If not, then a well chosen store-bought pretty looking pastry for dessert. (elegance is key!)
"If she's working or really busy and can't get a break, surprise her with her favorite coffee-break drink with a nice note written on the cup somehow, but don't ask her what she wants, KNOW what she wants." - LK
"Things that have a lot of thought put into them." - LA
"A date that includes a lesson in something she loves (ie. cooking, dancing, pottery, etc) or a list of the 'Top Ten Things I Love/Like About You'." - NM
"He got me the worlds largest red gummy bear because I love red gummy bears. That was pretty romantic. So the idea is: "take something she likes and buy her the world's largest one." - SZ
"Anything which is a total surprise, whether it be him showing up at my school unexpectedly to take me to lunch or bring me a chai latte just because." - LA
