Look at why you regret buying them, and with that in mind, look at avoiding that regret next time.
Eg, When I shop now, is when dysphoria ges is worst, because I have to take absences this body has nto account, and extra needs this body requires.
So Firstly I had to find out my Size. I got that down.
But even somthing in my size might not, cover my faulsies for example? I regret buying tops because they was in my size, and I still couldnt wear them. why? Oh yeah no coverage of my breast formes. so, Next top was like.
Do i like this? yes, Ok
Is it in my size? yes ok good
Now will it cover my lack of boobs yes. Ok ill get this. still regret it? yes. WHY? Because t see through.
What can I do?
I can wear a bra in same colour, or make sure as best I can that my next purches wont be see through.
So I like this red top, what if its see though, do I have a red bra.
Rince and repeat the process.
Also my most important question. Does it look as good on me as the modell.
You have to cater for your body, And buy things that you learn look good on you, and not buy somthing becuse it looks good on the models advertising it.
Which means, you got to reside to the situation, that somtimes that dress looks absoloutly amazing, but you like I, somtimes wont be able to pull off the look
