New binder sits weird?

hey yall,

ive been (shamefully) using a temu binder for the past half year. id been given it for christmas and it made me very happy. the seams already started popping(i mean what did we expect) so i decided it was time for a real binder. id saved up enough so it should be fine.

i got one from untag. the athletic leopard print binder. i out it on and! well it sits weird. it makes my chest go up and forward no matter how far i push em to the sides. i have tried all kinds of positions now that i could think of.

some extra detail that could be helpful is that i have very low hanging breasts. its a thing that runs in the family but also has gotten worse due to my quick weightloss the past few months. i measured the bust and underbust and got the appropriate size from their sizing guide. i didnt size up or down.

theres this weird dip right where the underbust elastic band is and it makes em look even more forward. it seems to work less than the loose temu binder somehow(i think maybe because the temu one doesnt force em up but rather just stops em from moving while letting em hang)

please if anyone jas any idea why its doing this ill forever be grateful
