Best friend is struggling to find a dress. It’s a small civil service followed by a big party with dancing. Summer wedding, she’s tried ‘proper’ wedding dresses and definitely doesn’t want one. Would like white,cream or pastel midi length, strapless or thin straps, not too poufy but easy to dance in. Can’t decide to go summer dress or party glam, slim and tallish, cost no limit within reason (not thousands) Problem is that anything online isn’t stocked so can’t try without paying £oos and then returning. Any suggestions? London based.
