I purchased these to replace an older pair of a similar style from Roman. These are so much nicer. The elasticated waistband is deeper and the length is not too long - just right for wearing with a not too high court shoe (I am 5'4").
I purchased the black and the navy and am very pleased with both pairs.
They are perfect for going out for a special evening.
I would say you could go down a size. I bought one pair in my size but the other colour was out of stock so I bought the smaller size and crossed my fingers they would fit. They did, albeit a little tighter, but not uncomfortable.
I adore these trousers! The fit, flare and fabric is wonderful. They are so comfortable and look so elegant : smart for work and lovely for evening wear with a nice top. Excellent quality and value. I would recommend them.
