What to buy ?

So few days back during sex i asked my wife to buy few sleveless dresses as she only wears traditional ones, i told her its an instant turn on for me and told her she can wear few deep necks, she told she is scared of ogling, i told she can wear them when i am around, to which she agreed and i suggested to pair it up with some nice push up bras. Yesterday i again bought up the topic with her, she just said she doesn’t have anything. So i started buying sleveless kurtas but once i started buying lingerie i got no clue what to buy exactly
