I need fashion advice?

I am a 41 year old petite lady. I am in a clothing rut, and am looking for ideas of where to buy some clothes that I like and will fit me. Can anyone please recommend websites of retailers that will have nice..not too frumpy, but not too trendy for someone my age? I want some fun pieces, but I don’t want to look silly. Thanks!!! p.s. not too expensive would be nice!
