Wanted: Simple/plain doll clothing for Barbies, Monster High and more

I'm looking for doll clothing! Anything relatively plain or simple, think everyday wear or things that do not attract too much attention. Some motifs welcome, just not over the top or too themed.

Dresses, pants, tops... even shoes - anything goes! Any brand! Bratz, Ever After High, LOL OMG... anything from curvy Barbies to tiny La Dee Da! (Modern and vintage equality good)

Also interested in random lots! (even if mixed with fancy items)
