Kitty one of the better ways around discovering and trying on new styles is to watch a programme such as QVC for some time.
Apart from the enjoyment of watching you pick up many tips along the way,all very helpful I have found.
Keep an eye on the models, especially those more your age and build,see what they wear well, and pick up favourite looks,then on sending for them you have a full month to test and try,even wearing garments out and about etc............yet you will have a full refund on anything you return that does not meet your expectations.
They have some "looks" that are for the cheaper purse, whilst there are some very upmarket styles with some top notch stylists.
Once you have chosen what look you like you can then mix and match,pay more for those pieces you will wear a lot,topped with cheaper or more expensive garments...........your own special look.
Good luck.
