well, I would say... braless
I would like her braless, but wearing a soft tight sweater with her hardened nipples quite visible.
A lace and orchid half shelf bra on a pair of small to medium boobs and the party is over!
My exact bra description is what SHE wore last night. Just put me in the corner, I'll be OK ......
I think it would depend on who she is, that is, what her breasts are like.
Braless in a nice form fitting top of any sort.
