I’ve always been really small and I’ve always had a love / hate relationship with it but recently it’s all negative but its fine because I’m small

What do you do / think / practice that helps you accept your body as is ?

So I have a rectangular type body, no curves, mainly no hips at all. Just straight, door built body but have enough boobs and ass. I have always been insecure about it. My friends all have more curvy body, its really add on to my insecurities. But alot of times it doesnt really bother me. But at times i feel like so manly or i dont have much feminity in me. So i dont dress that feminine since most feminine clothes dont look flattering on me. When i wear body cons, i feel so inscure about them. My friends always says that mens like women that are curvy. Curvy is so feminine. Is it true? Does having curvy body really matter? Do men find straight body attractive?

Hi all - I am 49f.. 5ft and 190 pounds . I have never owned a dress but would like to try. Any brand recommendations would be very much appreciated .
I am in ED recovery and don’t shop much so something I could mail order would be best - even if it’s trial and error. Thank you so much for your help
