you’ll probably be pleased to hear that men have a few rules too… Extract 3: David Stern, BBC Reporter, Kieve As for men, the advice was more basic. They should dress in trousers that break across their shoe fronts and their suit sleeves should reach the top of their palms. They should also not wear the same outfit two days in a row, the dress code suggested. Yvonne: Men shouldn't wear suits that are too small for them and, they should wear a different outfit each day. So Alice, what’s your reaction to that one? Alice: I think that's difficult for me because suits can be very expensive. It is true men don't look so good in suits that are too small - but I think I'd just say wear a clean shirt and a different tie and you'll look different. Yvonne: Good point. Now earlier, I asked which African country, following independence, banned its men from wearing the western style suit with shirt and tie to show it had broken links with the colonial past. Alice: And I said 'Rwanda'? 6 Minute English © bbclearningenglish.com , ссылка, 2010 Page 5 of 5 Yvonne: Hmm – good guess but it was actually Zaire, now known as the Democratic Republic of Congo. And there's just time now for a reminder of some of the language we came across in today's programme.
