I am a big size girl. Any tips how I can dressed cute and decent? I war most likely shirts and jeans.
You should be willing to experiment with a few things. Really see what your style personality is. And no matter your size, be confident in what you wear.
To start off with though, it wouldn't hurt to have a few essentials. A little black dress, a pencil skirt, a pair of jeans (and high quality, you really do get what you pay for!) a few plain colored t-shirts, leggings and a blazer. With the basics, you can dress them up or down depending on your footwear or jewelry.
I know Mercedes shops at Forever 21 quite a bit and they have a great plus sized clothing selection, if you want to check that out!
