From Marlies Dekkers Undressed, the black "White Stripes" hipster, wide sided G-String with white vertical pinstripes, style:  94451 and 15183.  These are low rise, with front panel with vertical stripes down to the back gusset seam and at the top, around each hip to a third of the way around the back.  Two vertical wide black elastic bands separate the pinstripe band at the top of the back from the open panel at the top of the G-String:  this open panel has the black narrow black elastic continuation of the waist band at the top, then two wide black elastic flat bands with white edging drop down towards the center where there is a black faux leather panel with "m/d" stamped in it.  From the bottom is the third wide black flat elastic band with white sides which runs vertically down towards the stem of the g-string with one narrow white pinstripe in it, down to the back gusset seam.  Then this open panel has narrow black elastic bands at the bottom which are a continuation of the sides of the g-string stem.

The waist band and front leg sides are all edged outside with a narrow band of black elastic.  This same narrow black elastic continues to edge the sides of the gusset and run up the sides of the g-string stem and then on under the bottom of the back panels, then again around the hip sides to become the front leg sides, in one continuous loop.   The gusset is lined inside with black cotton.

These G-strings are simple at the front, dramatic at the back, they feel soft and stretchy.  This particular item can work with many of the Marlies Dekkers black bras as well as with the "White Stripes" collection.  The fabric consists of: 78%Nylon 13%Elastane 6%Cotton 3%Polyester and these thongs may be machine or hand washed at 30 degrees,  no iron, dry cleaning, tumble drying or bleach.  New and unused: The model wearing the g-string in the images was given the g-string she modelled. The retail price was £33.00.  The matching bras, waspies and thongs and suspender thongboys are listed separately.
