Went to your web site and saw you last jesey/bib design and think they are way cooler. I mean, the name and logo shape are nice
and they are used to good effect there.
You say yo want to go "plain", but plain with loud colors is, well, loud. The light blue jersey and dark blue jersey don't play well with
the red accents. To go "plain" and be tasteful at he same time would entail toning that color choice mess down a notch.
And yeah, it does sync with Rapha way too much, you just have a brighter, louder, clashing version of it going on there.
You nailed it on the construction, like all of what you chose there. I buy way to much cycling clothing, some of it custom from Voler, Verge, an
I order kit with full zipper, high end pad, flat lock seams, etc...
Recently recieved 44bike kit from Voler, a jersey from Pactimo and a Sachs skin suit made by Verge.
If you want to be plain and different, work with black base/silver high light/white panel and use your logo graphic in red to better effect.
Alternate next set by goung white base/silver high light/ white panel and again keeping the logo red. The design and placement of the logo should be your focus.
If you're going powder blue, dark blue and pink, jazz that pallet up with some graphics
I think you're running from something like this, and rightly so, it's messy:

But taking the graphics away and leaving a white stripe doesn't sex that up.
Less grahipcs, but with a better design is what you're after.
