^I agree with your post completely!
Red lipstick is awesome, you can wear the simplest outfit with it and make it look chic and fresh. I love flats and skirts too, and I wear them all the time, even though it makes me look even chubbier. And teal is one of my favourite colours for winter!
By the way, if you're still looking for that denim jacket, I would wholeheartedly recommend this one from ASOS:
http://www.asos.com/ASOS/ASOS-Denim-...lr=Vintageblue It's amazing value at a great price, really nicely made, the quality is great... It's thick and oversized, you can go down a size if you'd like it to be more fitted. They have a Petite version as well. Definitely one of my staple pieces for this spring.
Now I just have to tell you guys that I found the perfect T-shirt! I had been deciding between a Gina Tricot one and one from T by Alexander Wang, when I stumbled upon one in Zara and it's really lovely. It's slightly sheer and oversized, so I can wear it off the shoulder if I want too. The material is viscose, though, but I don't care, it feels great. And just 14,95€!
I might get it in grey and white too. I'm still building a basic wardrobe and I don't have ONE t-shirt.
