I have written about Baukjen before, it's a brand that i have only really come across this past year but that i have been really impressed with. They do great quality, versatile basics that can be dressed up and down, that wash well and last.
I have some perfect leather leggings that i got last year and lived in, i think they were my most useful item of winter clothing - definitely worth the investment. I have also recently got a mint green leather biker jacket (of dreams), the leather is so soft and it fits perfectly.
The other thing to look out for is matching tops/ shirts and trousers which are great if you are a different size on your top to your bottom and can't find a jumpsuit that fits - if you get them as separates it gives the illusions of wearing a jumpsuit but will be your perfect size.
