Although the legs are apart, the placement of the models hands and the relaxed pose, with the model looking away thoughtfully, do not make this a sexually charged image.
More close up composition works with this image as it means the legs do not look out of proportion and there is more emphasis on the lingerie.
As the lingerie is black, it works to do the image in black and white – this gives a more timeless, classic feel and picks on the contrast more prominently.
