The redhead (or brunette, it all depends on the lighting) I referred to spent the first two acts in a bikini top and a dress on with nothing underneath so you got to see everything from the waist down in glimpses. Breasts covered at all times.
She came into her own, though, with a central role in Act 3, with a major role and a loincloth and topless with a fur stole around her shoulders. The fur stole didn't cover much and she eventually gave up trying.
Many of Teatro Oficina cast members are esteemed Brazilian actors with a long history in theatre, TV and cinema. My thoughts is that this lady, a mature lady in her 40s, perhaps?, unnamed for now, was possibly doing her first nude role tonight and a little bit coy about it but merrily got into it as the evening progressed. Looking forward to seeing her 'develop the character'

in subsequent performances with the fir stole and loincloth left in the dressing room.
