So i ordered a new singlet it came in size medium but i have a big problem. The area where the ribs are exposed i feel like is so stretched out, however on my legs its very long going over my knees its mildly tight on my chest and back area as well. I dont know if singlets have different cuts or whatever but if anything i just need a solution on how to make that area go more up instead of being so stretched out
