Armani actually has two shows today, 11am and 12pm (a lot of shows in Milan do this). Strictly speaking this is a live stream of the second show, but I suspect they probably record the 11am show and pass it off as a live stream of the 12pm show.
Biagiotti is an odd one. The website says 'live' but the time says 17pm, so I assume they just mean 17:00hrs. Wish they'd be clearer about what exactly they're doing.
