With a t-shirt on and no bra. Frequently have sex with her keeping her t-shirt or camisole on, but being fully naked otherwise

A long skirt with no panties.

Skirt with thong, slide up, and side.

In winter keep top and socks on your body.

You can have quickies in places if she wears the above dresses which allow clothed sex.
