Does anyone have these? What are they like? [[http://www.gap.co.uk/browse/product.do?cid=1000005&vid=1&pid=000600629008 here]] They seem a bit high waisted - are they? Low rise is much more flattering one me. :) And finally - no idea what size to order! I'm always a 10 in gap, but no idea about this waist measurement.... TIA
