So my GF is sometimes not very confident. For example I bought her a new shoulder bag for her birthday that looks very feminine (rose-pink, expansive brand). She was very exited when she got it and she has worn it all the time until her birthday party some days later. On that day she hid it and didn't tell any of her friends because thay would say it looks a bit bitchy. Other examples are that she doesn't ofter wear figure-accentuating closes although she is in good shape and has a nice body. So on the one hand she isn't really aware of her (nice) body and on the other hand she is afraid of her friends thinking she looks "bitchy".

What can I do to help her (and me)?
