Re: new dresses trend
theres diff trends. the shirts are much more longer in karachi than in lahore and islamabad, but they are definitely long everywhere with all kinds of styles for the trousers. no patialas thats for sure.
tulip pants are just trousers with a pinched pleat near the waist (the silhouette is like that of an upside down tulip at the hip, so it kinda has a puffy look at the hip). the paincha is usually cuffed.
you have to be careful and not have them looking like harem pants, which are too filmi for my liking.
the properly tarilored version would look nice with a dheeli kamiz.
