Shirt fit critique / troubleshooting

[GloStiX]

Specifically the horizontal back creases, which I know can be from the shirt being too tight around the waist, or too much taper from the chest. My lower ribs also flare out a bit, which doesn't help.

I've tried adjusting shirt length to i.e. lower the waist point, doesn't help. I'm wondering if I have to increase the chest (and waist?) measurements, but I want to avoid having a billowing folded-over ring of fabric above my beltline, since I'm slim and don't want to look like the Michelin man .

Can I adjust the front-rear balance so there is more fabric across the front of the shirt and less on the back? That feels like what I want intuitively, but not sure. Would appreciate any opinions.

Exhibit 1) Blue shirt: thick fabric, longer shirt length, very noticeable.


Exhibit 2) White shirt: not as bad, just due to thinner fabric?

The shirts are really tight across your chest and abdomen. Almost skin-tight it seems. The horizontal lines across the lower body are more a sign of tension IMO. See how they wrap around your lower body on the side views of the blue shirt at 0:02 and 0:16. How much ease do you have in your shirts i.e. how much more do they measure around the chest and waist compared to body measurements? I would guess it’s less than 3”. Yes, you can add material to the front of the shirt.

Armhole looks too high. You have a massive drop between your shoulders and waist. It wont be easy to assess that without giving a little more room around the waist.

Did you wash the shirts a couple times ? Because, with such slim fit, you wanna make sure it won't end up too small after 10 washes.
