Here is a series of pictures showing all the new jerseys that will be used in the upcoming Bundesliga season, from kicker.de.
Some teams went with a more classic look (like Bayern), others decided to try something new (Gladbach), most didn't change all that much, while some seem to be having a contest for who will have the ugliest jersey in the league.
Here are some of my thoughts:
Jerseys I don't like
Schalke's away jersey (page 8) isn't horrible, but I really don't like the dark V-neck look.
Freiburg's home jersey (page 9) isn't the greatest look, but their away jersey (page 10) is just nasty, trying to look like some of the recent ugly Barcelona shirts.
Hannover's away jersey (page 17) makes me want to puke.
Werder Bremen is trying a green version (page 27) of the table-cloth-looking Manchester United jerseys from last season, but their away and alternate jerseys look completely different (and much better).
Hertha is trying to induce vomiting with their orange away jersey (page 34).
Jerseys I like
I like Bayern's new classic home jersey (but I still hate that white and orange abomination of an away jersey).
Frankfurt's away jerseys (page 11) look pretty cool.
Stuttgart went with a nice classic look (page 23), but with thin horizontal stripes (not bad).
Mainz's away jersey (page 26) looks bad-ass, even with the pinkish accents.
