Camera Timer

Among the several problems faced when one does the dressing alone, is at the time of taking pictures.
First you need a tripod, and a remote shooter or like in my case since I don't have one, use the timer on the camera.
Thing is, I don't really know how many seconds it gives you, but sometimes the timer beats me.
So the picture is taken with me showing too much, moving resulting in a blurred picture, or like in the case of this pic, in a really extrange position.

So any tips??
