Coat/Jacket Help!

[Wilberforce2]

I'm so crap at knowing how to dress, I need help!

I'm a fat (size 16 bottom, 18 top) just turned 40 mum of two and spend my days in jeans, baggy tops and converse. The weather is getting warmer so my big padded hooded parka is "too wintry" but I have no idea what kind of jacket/coat I need and that will look ok. What are you all wearing now that the weather is changing?

Thanks!

I'm wearing my biker jackets with jeans. Both fake not real leather.

A black crew neck size 16 one that I got in Dorothy Perkins which is actually too big, & a grey size 14 one I got in Wallis.
