Lady Gaga freed the nipple yesterday in London. The singer has recently been seen wearing some more conservative outfits, had us wondering if her engagement had prompted her to cover up. Evidently not as Gaga stepped out in all her glory last night. The clothes were off as Lady Gaga went for a midnight hat fitting at the Phillip Treacy Victoria, London store. She wore a sheer nearly naked black dress with some highwaisted knickers an pasties to cover her nipples with some eye catching Saint Laurent shoes Her eye make up was dark and smoky with some drastic black eyebrows. She later covered her blonde bun with an ostentatious feather hat from her shopping trip.
