Sometimes being a little selfish isn’t a bad thing. Especially when it comes to how you dress and present yourself. It should always be for yourself, to make yourself happy and feel good.
I saw a movie, documentary really a few weeks ago, called Embrace. It talks about women accepting their bodies just as they are, loving them for what they’ve been through, what they can do and will continue to do for you. Why allow someone else to tell you what you can and can’t do and can and can’t wear? If it makes you happy, just do it!
If you want to wear a bikini at the beach, do it. If you want to wear red lipstick then just do it!
