Wearing Buttoned Ihraams

The prohibition of wearing sewn clothing in the state of Ihraam refers to that clothing which is tailored to fit the parts of the body (i.e. Kurta, Izaar, shirt etc.) or bears a resemblance to this type of clothing. Therefore, if someone was to take a sewn article of clothing like a shirt, coat etc… and just put it on his shoulder–not wearing it as it is normally worn i.e. not putting the hands into the sleeves etc. he will not be liable to any penalty; although the clothing article itself was a sewn article of clothing. 

However, if someone was to get two pieces of cloth cut out in the shape or a Kurta, Izaar, shirt etc. (which are not sewn together) and has to attach them in some way (either by using Velcro or some other material) and then wear them the way people normally wear these articles of clothing, he will be liable to a penalty; although it was not sewn together. 

One more point that the Fuqaha have mentioned is that if a person has to take a normal, simple Ihraam (i.e. two pieces of cloth) and attach a button, safety pin, string (elastic) etc. to hold it up, this will be Makrooh.

Due to not having a full picture of your ‘Ihram’, we are unable to explicitly answer your question. If it is two pieces of cloth that are not tailored to fit the parts of the body and they have buttons to hold them up in place, it will be Makrooh to use them as your Ihraam. It seems that the picture you have sent has a tailored waist for a lungi. It will not be permissible to use this as it falls under sewn clothing.
