ok girls I got one of those T back convertor's and it does the job. My bra straps stay in place now I can move around in all sorts of positions without worrying a bra strap is going to pop out anymore, they are a bit uncomfortable tho and certianly hard to put on and adjust whilst wearing the bra. Overall I probably still prefer wearing the strapless as I have got used to it now and I have never had a comment about it drooping down whilst I used to get comments about my bra straps falling down, it is amazing how many people noticed considering my bra straps were always only down for a few seconds at the most. The lady I spoke to on the phone wear I got the strap convertor from suggested my current bras might simply be worn out since they all over 6 months old (all 2 of them LOL) in fact one of them is nearly 2 years old and before I got my strapless I was wearing it a lot. She tried to then sell me some new bras but I told her thanks but the bras are I got are comfortable, was just a problem with the straps which is now solved by the convertor so I effectively have made these bras longer life now. When I am not around others I can wear them normally without the convertor and is just a minor inconveniance to fix the straps when they fall down. If someone comes round whilst I have one of my old bras on without the convertor I will either not worry depending on who it is or just stick a shirt or something on so my arms are covered. I usually push the straps as far up my shoulder as they can go anyway before opening the door so they are fine for that, its just if I have to drop my shoulder or the person is staying round for a bit. So to me I am happy now and with only buying 1 new bra in the process.
