Can alterations fix this: lapels bow out, belly stretches forward, diagonal wrinkles on shoulder, vertical wrinkles on back (photos below)? How hard/expensive is it to fix? The issue occurs with all OTR suits for which the shoulder width fits (tried dozens). If I hunch my shoulders forward, the problem mostly goes away.
there is no way to make that wearable.
I dont think your posture is that odd .
take a photo in just a shirt and pants.
and relax during the photo
