Hi Yasu,
that's a very good question! Everyone is normally asking about the look, the quality and the shine of latex fashion. So asking for the feeling is something new. And yes, the feeling of latex is different.
Like the shine and look of latex the feeling depend on the quality of the material. Some "cheaper" latex the shine is mostly not that perfect because the surface is not so plain like some better latex. That's also the same what your girlfriend would notice if she wear the latex. If you wear some better latex stockings, gloves or whatever it can feel softer or not.
Furthermore, it's also a difference if you buy some thicker material. This material is not so flexible and soft like thin latex. But also if you have the same thickness of latex the quality makes differences if the it is more stretchable or not.
Finally, wearing latex is always a great feeling. So these differences are small compared to the difference of wearing latex or cotton

kisses
