I haven't heard of Optifit bras - have they been personally recommended to you.
I am large in the frontal area, like a ship in full sail, so must have an underwire. Also have a problem with straps that fall off the shoulder.
Last week I decided to clear out all my M & S bras that only nearly fit and can be uncomfortable, and my Fantasie bras that are comfortable but are washed done. I'm 65 and want comfort and a decent shape. Pretty lingerie would be a bonus.
I went to the specialist bra fitting shop of the area, who provides all shapes and all sizes, to buy 3 bras, one black, one white and one nude. They pride themselves in their ability to provide a great service.
Yeah.... you think !!
Generally it has been a 36G or GG, or a 38G. I'm relatively narrow in the back and need good fitting to prevent the booby weight from pulling the back of the bra upwards. To make sure that the wires at the sides aren't poking into my underarm, but also ensure that there is no -fat- overspill at the sides, ensuring that the wires fit into the chest bone and a full coverage cup with no extra booby at the front.
Ahhh.... we found one bra. It isn't particularly pretty but it is sooooo comfortable.
Fantasie Speciality Bra which was much cheaper than any of the others at only £23. Excellent fit and comfy.
I kept a couple of pretty bras but for general wear I could recommend the Fantasie Speciality as being worth a try on.
