I absolutely love the story behind the photo on the left with my grandma wearing the blue bridesmaid dress
Her advice pretty much boils down to something that's classy, comfortable and, preferably, floor-lengththough as you'll soon see, there is a little wiggle room
If you're still undecided, try imagining your maids in these pink bridesmaid dresses that are designed to impress: Another trend you might consider is floral print bridesmaid dresses

If the Invitation Asks for Cocktail Attire, Men Should Wear: A dark to mid-gray suit A button-down dress shirt in white or another muted color A necktie or bow tie in subtle patterns or plains A simple pocket square Black dress shoes with a leather sole, such as oxfords Over the calf socks that either match your trousers or pick up something in your outfit such as a color in your tie or bow tie Of course, make sure you are clean shaven and you have a recent haircut Cocktail Attire Donts: DONT wear your tuxedo or white tie, as that would be too formal for this dress code DONT wear a black suit these should be reserved only for funerals DONT wear your pinstripe suit, bright colored ties, a bold paisley shirt, or flashy accessories at home to a wedding the couple should be the center of attention, not you DONT wear casual clothes such as khakis, chinos, jeans, polo shirts, or a sports jacket
I think you could play around and size up depending on you personal comfort levels
Or style it down for a causal day with sneakers and a denim jacket
