Appropriate wear for the event

The BBC has an article by John Simpson about the inevitable Ukrainian withdrawal, in the face of superior Russian force, from the Crimea:

The Ukraine is drawing up plans to withdraw its soldiers and their families from the Crimea, according to Kiev's security chief, Andriy Parubiy, who said they wanted to move them "quickly and efficiently" to the Ukraine mainland.
Earlier, pro-Russian forces seized two naval bases, including the Ukrainian navy's headquarters in the Crimea. Kiev says its navy chief has been detained. It comes a day after Crimean leaders signed a treaty with Moscow absorbing the peninsula into Russia. A referendum in the Crimea, approving its split from the Ukraine, came nearly a month after Kiev's pro-Russian President Viktor Yanukovych was replaced by Western-leaning interim authorities.
In modern times, Moscow has staged three major invasions: Hungary in November of 1956, Czechoslovakia in August of 1968, when the Communist governments there began showing dangerously Western tendencies; and Afghanistan in December of 1979, when the pro-Communist regime was on the point of collapse. These were huge and brutal operations, involving large numbers of tanks, and sometimes great bloodshed. The takeover of the Crimea has been completely different. This was an infiltration, not an invasion. And unlike in Hungary, Czechoslovakia, and Afghanistan, it was welcomed by a large proportion of the local population.
NATO Secretary General Anders Fogh Rasmussen has called the crisis in the Crimea "the gravest threat to European security and stability since the end of the Cold War".
There were charged exchanges in a session of the UN Security Council, during which US envoy Samantha Power said her Russian counterpart Vitaly Churkin "showed more imagination than Tolstoy or Chekhov". "Russia it seems has re-written its borders but it cannot rewrite the facts," said Power, who was then accused by Churkin of dropping "to the level of the tabloid press".
Parubiy, in a news conference, set out more details on Kiev's position in light of the events in the Crimea. He said arrangements were now being set up to introduce visas for Russian nationals traveling to the Ukraine, and he said Kiev was seeking UN support to "proclaim the Crimea a demilitarized zone", which would involve the withdrawal of Russian troops and the "relocation of Ukrainian troops to the continental Ukraine, as well as facilitate evacuation of all the civilian population who are unwilling to remain on the occupied territory".
The Ukraine is also leaving the Moscow-led Commonwealth of Independent States (CIS) alliance, and is preparing for military exercises with the US and the UK, Parubiy added.
With reference to plans to withdraw troops and their families, the Ukraine's interim Foreign Minister Andriy Deshchytsya told the BBC that they would not be forced to leave if they did not want to. But, he said: "The situation is unpredictable and uncontrolled sometimes, so that's why there is a danger also for the civilians".
Meanwhile, a deadline of 19:00 GMT, set by the Ukraine's interim President Olexander Turchynov for the release of Navy chief Serhiy Hayduk has passed. Shortly afterwards, Russian Defense Minister Sergei Shoigu called on the Crimean authorities to release him.
A defense ministry statement said Commander Hayduk had been obliged to carry out orders in accordance with Ukrainian military regulations.
Turchynov earlier said that unless Serhiy Hayduk and "all the other hostages, both military and civilian, were released, the authorities would carry out an adequate response... of a technical and technological nature". It is not clear exactly what he means, but it could involve the electricity or water that the Ukraine supplies to the Crimea, the BBC's David Stern in Kiev suggests.
Kiev said Hayduk was detained soon after the Ukraine's naval headquarters was stormed by some two hundred pro-Russian activists, some armed, in Sevastopol, the port city which is also home to Russia's Black Sea fleet. They were filmed going through offices, removing any Ukrainian insignia, and replacing the Ukraine's flag with the Russian tricolour.
There were cheers from the crowd when Russia's Black Sea Fleet commander Aleksandr Vitko arrived and entered the building. A handful of Ukrainian servicemen have refused to surrender. One told the BBC's Mark Lowen that they had been told to stay overnight to protect the equipment but fully expected to be told by Kiev in the morning to withdraw.
The Ukraine's navy base in Novo-Ozyorne in the Crimea was also infiltrated after a tractor was used to ram the front gates. Some fifty Ukrainian servicemen were seen filing out of the base.
Ukrainian Defense Minister Ihor Tenyukh and First Deputy Prime Minister Vitaly Yarema reportedly tried to enter the Crimea to defuse tensions, but were prevented from doing so.
Earlier, Russia's constitutional court approved the treaty absorbing the Crimea into the Russian Federation. The treaty now only needs ratifying by parliament, which correspondents say it is certain to do.
In an emotionally charged speech, President Vladimir Putin said the Crimea had "always been and remains an inseparable part of Russia".
Meanwhile, shocking footage has emerged of MPs from the Ukraine's far-right Svoboda party roughing up Oleksandr Panteleymonov, the acting chief executive of the state broadcaster, over his decision to broadcast the treaty ceremony in the Kremlin.
The crisis in the Crimea is expected to dominate a meeting of European Union (EU) leaders, who meet in Brussels, Belgium on Thursday.
UK Prime Minister David Cameron said the EU must send "a very clear warning" to Russia, raising the possibility of further sanctions against Moscow. He also said the G8 group should discuss whether to expel Russia "if further steps are taken". Moscow said any expansion of sanctions was "unacceptable and will not remain without consequences".
UN Secretary General Ban Ki-moon is heading to the region. He will meet Putin in Moscow on Thursday and the Ukraine's interim leaders in Kiev on Friday.
Pro-Russian forces effectively took over the Crimea, with its predominantly ethnic Russian population, after Yanukovych fled the Ukraine on 22 February 2014 following protests in which more than eighty people were killed.

Rico says he belatedly realized that the Russians (photo, above) are all wearing (appropriately) balaclavas, given the weather and, presumably, to prevent recognition in photos like this one...
