Dress and its fashions

Long time ago when I was working in a VA Hospital, there was a sign by the elevators saying
"Visitors wearing only undershirts and nickers will not be allowed in the hospital"
Or something like that. In those days only the vacationers wore undershirts and "nickers"(Half pants). Of course many other changes have been observed from old days in the dress of man and woman young and old.
Strangely
The man's dress has always been shirt and neck tie + trousers and when needed a jacket (and a felt hat or hat for men) and women's dress has always been open neck with variable view of her "beauty below the neck" (This part has not changed over the centuries.)
(Islam has curbed the neck and below the neck open-ness.) Here I have a story about women's dress, please bear with me.

I was in England when Sir Francis Chichester was knighted by Queen Elizabeth II, after he completed his (single-handed) record breaking round the world tour in his boat (called Gipsy Moth IV). There was a great welcome for him when he landed in July 1967 at Plymouth and then he was knighted with the same sword which was used by Queen Elizabeth I to knight the 16th century well-known navigator Sir Francis Drake. Now this was a very special occasion and Mrs. Francis Chichester was there also to be presented to the Queen and guess what, she was wearing a 'Pant-coat suit' (believe it or not).
The newspapers made a lot of noise, I remember," What? pants on a woman with a situation like that? Never heard of such audacity".

Man's trousers have been undergoing recent changes from full pants to half pants or even less and below the knee coverage up to 3/4 th pants also (for lack of better descriptive language)
I see Muslim boys coming into masjid and those who are familiar with the subject I find them trying to unsuccessfully cover the knees with the "higher pants" when 'sitting' in prayer. I have not observed too many "torn" jeens at the knees. Adults, I see in the masjid many a times with half sleeve 'undershirts' pretty loose and extra-large variety, which is frequently being worn these days as an alternative to the real shirt with collar etc. Well, I dare not say too much in case I am ousted from blogosphere.
Most objectionable aspect of dressing in women (from Islamic point of view) is that the shirts or its equivalents are too tight and same is true about the trousers, but gnerally I see Muslim women keep the shirts and trousers loose and do take care of their "satar".
May Allah forgive those with changes in dress for men and women among the Muslims that do not conform to His restrictions.
