hey hun....
i got engaged a few months ago and went shopping in birmingham...bought a light blue lengah for the engagement. cost about £240.00. i think it was a lil overpriced but was just rite for the occasion.....skirt and top were full of kaam, and the duputa had a medium sized border...matched it with blue and silver jewelry.
i think you should try and go for lighter/softer colours for the engagement....but then again go out and try on a few diff outfits and see wot looks best.
good luck. x
