I think color is gender neutral. All that stuff about pink for girls and blue for boys has created a world where girls want all things pink and no toys that are about science or anything.
Let me get off my soapbox about messaging and return to the question at hand:
I think that if a man looks good in that color blue, or in pink, then it is perfectly acceptable for him to wear it. Women wear blues, and how many if us like olive drab or military greens as one of our neutrals? If you wanna talk about traditional"feminine" colors, military green probably isn't one of them LOL. Some of the most nicely dressed men, or most attractive, or eye catching, or whatever you want to call it.... well, they're wearing pinks or other colors that aren't stereotypically "masculine". Of course, that's my opinion, and as such, YMMV.
And I agree with Rachylou: that's not exactly Tiffany blue to my eyes (could be differences in monitors or whatever). That's more swimming pool blue or Caribbean or something. I think it looks good, whatever color it is technically called.
