L., right? I can't believe it - she's always so sweet at the park with her daddy. Does she only do this with you and is perfect with daddy or is this way with both of you?
My DD, Danica is also 2 and very much wants control. I handle things two ways. Most of the time, I let her whine and then change the focus. So she doesn't want the sweatshirt but it's already on, so I say look at the fish on the sweatshirt or it's time for sesame street and waffles, or let's wake up daddy. Then she forgets all about the sweatshirt.
Other times, I let her take the lead - ok, no sweatshirt. I've even driven her to school without a jacket b/c it's not worth the argument if I warm up the car and run her into the school. She has the same thing for breakfast and dinner everyday. I can't prepare something, have her not eat it and prepare her usual. So, I just let her tell me what she wants. Some moms might say that's terrible - but she's a wonderful eater - tastes new foods, loves fruits and veggies, so I'm not going to argue with her about it. She tells me what she wants, I give it to her and she feels like she has a little bit more control over her life.
Basically, I'm suggesting don't battle - don't engage. Be happy and cheery and amenable and maybe she feel more in control. That's what it's really about - she's starting to assert her independence. Open the cabinet and say "which cup do you want"? Yes things take a little longer, but she'll feel good and so will you. Hope this helps.
BTW, we should get the girls together for a playdate on the weekends - especially in winter - it's tough not being able to go to the park. Good luck!
