Calzedonia, the Italian hosiery and beachwear firm, have a really good selection of leggings, including leather-look and denim styles. I chose this pair in mock-croc leather material, which I liked because they were a little different and less glossy than plain leather-look leggings.
Leggings, skinny jeans and bodycon dresses all need a smooth base. There are lots of sleek bras and knickers in the shops now, which aim to give a smooth foundation. Extra help is also at hand from shaping underwear and tights designed to flatten bulges and support bits that are not so firm. H&M do a very good range, including Shaping Briefs that sculpt the stomach and hips and various tights that deal with stomachs, bottoms and thighs. Both underwear and tights are all made in materials that are sleek and silky in texture and look attractive in black. These 30 Denier Shape Up Tights Bottom Lift in the picture below are an example.
So it's not so hard to be smooth!
