I bought the lace top from Sirens in the winter last year, and the bra is just a strapless black bra from La Senza that I've had for ages.
The shorts are my usual high-waisted cut off shorts from last summer, they're not so comfortable, but I love them anyway. The tights are Secret.
The sweater in the fourth picture is one I bought from the Salvation Army last... fall... I think?
And the shoes are my black ankle-strap heels from last summer!
