... is there such a thing?
I noted the Christmas princessing thread and want to be less of a frumpy fat blob by Christmas. I plan to go to fitness classes twice a week and generally do more walking with DD in the buggy... but there are mirrors EVERYWHERE at the gym and I can’t stand catching sight of myself dressed in saggy New Look leggings and an oversized T-shirt. It’s too demoralising 
Can anyone recommend a shop for some flattering work out clothes? I love the look of Sweaty Betty but budget can’t quite stretch to that sadly.
