Britney Spears has been indulging in a little retail therapy.

The “Oops, I Did It Again” crooner celebrated dropping down to a size 6 by dropping nearly $10,000 on hot clothes in one hour at Barneys in Beverly Hills, according to In Touch Weekly.

Spears specified sexy yet casual clothes — but no tracksuits, a staple of her post-pregnancy wardrobe, according to ITW, which reports that Spears loaded up on soft, clingy cashmere sweaters.
