My (33M) wife (33F) wanted "an experience" and now I feel humiliated

My wife wanted to go on a special little "romantic-ish getaway" with me and our infant daughter (4 months old). We live near Chicago originally, so she wanted to go back to Chicago, which is about a 3 hour drive, and go to some of her favorite places. I grew up in the suburb right next to Chicago. I was happy to do it, and we had the money to do it, so we did it. We decided to stay in one of those trendy boutique hotels because it felt like staying in Chicago. We also have a dog, but we only brought our baby and left the dog at home.<br><br>One of the things she wanted to do was go to Millennium Park. But she didn't want to do an ordinary visit there. She wanted to dress our baby up as Lady Liberty from a painting by Delacroix, and she wanted me to dress up as Marianne (I didn't know either but it's some female personification of France). She wanted us to walk around the park like that. I tried to explain to her that 1. it was cold (it's already cold in Chicago in October and we went outside in the morning) and 2. I didn't want to do it. She started pouting and giving me the sad puppy eyes, telling me it was just 15 minutes tops and how it would be "fun" and "an experience". And it would be good for our kid, to have us all match and show her all the sights, and take photos to look back on when they're grown up. I tried to tell her that the kid doesn'n understand any of it, but she said that she at least could cherish the memory of it, that we had done it. She'd been planning it for weeks, so I knew I couldn't say no, and I didn't. I don't know why I said yes, I just did.<br><br>We went and did it, and the experience was humiliating and I regret it. And I told my wife so. Even though we were both wearing street clothes under the costumes, I was freezing my ass off in the chill October morning of Chicago. On top of that, there were a lot of people there, and I saw at least five people laughing at me. A couple of people asked if we were headed to a costume party, and I had to explain we were just doing this for "the experience". Two people stopped us to compliment my wife's painting and ask to take a photo with us for their kid. I felt like a prop. When we were done, we went back to the hotel to change and my wife was beaming, saying how much fun it was, and how nice it looked, and how the photos would be wonderful, and I snapped and told her how humiliating it was. She started crying, saying I ruined the day and I was being mean, and we've been fighting about it ever since we got home. She says she can't believe I would be so selfish and unromantic when she planned it all out and it was just 15 minutes tops anyway. There were a lot of other little incidents on top of that during the trip, and I just don't know what to do. I want to just forget about it and move on, but she keeps bringing it up.<br><br>How can I make her feel better without having to do more humiliating activities? Or should I just do it? I mean, it was only 15 minutes, what if she wants to do something else? I just don't get why she is being so stubborn about it.<br><br>TL;DR: My wife wanted to do a romantic-ish getaway and wanted me to dress up as a national personification (Marianne) and humiliate myself. I did, and I regret it. How can I make it up to her without having to do something like it again?<br><br>EDIT: Jesus, thanks for the awards. I didn't know this had gotten popular. I wrote this on the mobile app, and there's no notifications on the app. I'm going through all the comments. I'll try to respond. I apologize if I don't get to yours specifically.<br><br>To clarify a few things. Yes, I did take a photo of us all at the end, as she wanted. I did it because it was what she wanted, and I knew she'd stay sad if I didn't do it. Yes, my daughter was pretty much just sleeping the whole time. It was cold, and there was a lot of noise, so yeah.<br><br>And lastly, to clarify the painting, she wanted to dress our daughter up as the Goddess of Liberty from the painting "Liberty, Leading the People" by Eugene Delacroix. I know it's technically the personification of the concept of Liberty, not Lady Liberty. I think it's because most people only know the statue of Lady Liberty and not the painting. That's why I made the mistake.
