However, thinking critically, what are the odds that these colors just happen to perfectly align with the Ukrainian flag? Also, I've never see any space suite, from any country, in a yellow color. I've at least attempted to find evidence that they've used yellow suits before, but haven't found any. At this point I feel like I'm trying to prove a negative, and would ask anyone who claims that these yellow suits have been used before to please provide evidence.
On the other hand, I doubt those space suits were made in the last 2 weeks.

Reading the above article on the subject I notice a few interesting things. First, the suits were allegedly made some moths ago in the colors of the crews alma mater. They all have the same alma mater? Seems strange.
Second, the article says: "Every crew picks a color that looks different. It was our turn to pick a color," said the cosmonaut. "The truth is, we had accumulated a lot of yellow fabric, so we needed to use it up. That's why we had to wear yellow flight suits." -- They got to pick their colors, and picked yellow because they had extra fabric and HAD to choose yellow? This seems self contradictory. It also doesn't mention alma mater. There's 3 different explanations put forth by the article.
To top it all off, I haven't seen anything about these suits having existed since 2015 like you claim.
I'm not convinced the suits of a space agency were really determined by the amount of excess fabric they had lying around.
