There is a hobbit writing a certain book about a certain adventure. His pipe in his mouth, his candles lit, his thoughts thinking, and the ink dripping onto the paper that reads:

"...during dinner, the Company and Bilbo met various members of Elrond's house, and the hobbit, who had never met an elf before, soon discovered that the elves were very different in kind: some of them were as joyous as children, and some as regal and noble as kings of old. 
The elf sitting next to Bilbo was one of the latter and he introduced himself as Haerelben, and no title or surname was given to Bilbo to use to address them. The hobbit was starting to think that elves either didn't care about such things, or more likely, they were not used to not being recognized immediately."

"He was tall among the Quendi and firm like a tree, with fair skin and gray eyes as the clearest pebbles of the clearest river. A subtle light emanated from him, up from the crown around his head - which Bilbo could venture to guess was made of metal and glass- down to the inner silver robes under his midnight blue clothes. He wore his hair loose, flowing down to mid-back, braided and adorned with blue gemstones, and its color was..."

Now, here is where the hobbit hesitates...

'What color was his hair? 'he murmur '...blonde? I can't just leave it like this. It would be a disgrace to all descriptions.'

He groaned and tugged at his hair.

'I can't describe it as "strawberry blonde" either! I can't use that word to describe an elf lord. I would die of indignity if they found out!' he exclaimed.

Whining to himself, the hobbit takes another piece of paper and continues writing, hoping to find the right words later.

"... He was kind in their conversation and very polite, but Bilbo didn't see them smile even once. Later in his stay, he would discover that the elf lord found joy in surprising wandering and distracted hobbits who were strolling through the magnificent halls of Elrond's house, as it seemed the elf lord, like most elves, had a special talent for blending into the surroundings and Bilbo didn't expect the tapestry he was admiring to start talking back..."

The hobbit pauses again and mumbles indistinguishably to himself. He reviews the recently written paragraph and begins to cross out words and rewrite sentences.

After a while, he pulls in the previous paper and writes:

"...He wore his hair loose, flowing down to mid-back, braided and adorned with blue gemstones, and it was, of color, like the autumn leaves of the trees in the elves' garden under the sunlight..."

'This saves both our dignity,' he proudly declares, resolving the issue.

........

Later, it seems that this section was removed from the Red Book, most likely because upon Bilbo's return to the valley, a perfectly good supper was unjustly wasted in the river when what initially appeared to be a young birch tree, against which Bilbo had leaned, moved and turned out to be said elf lord which greatly startled the hobbit.

Moral of the story: Never cross a hobbit about their meal, or they'll write you out of their famous tales.

Quickly notes on appearance for RP purposes

It is said that the beauty of the Eldar had not decayed since the first ones woke up at the shores of Lake Cuiviénen, either not their power... that instead, the elves that remain in Middle Earth grow tired in comparison to those who traveled to Aman for those stayed strong and rested through the years.

Face:

Long ageless face with a broad forehead, high cheekbones, and pointed chin.

Long hairy eyebrows and clear eyelashes.

Wide mouth better suited for smiling though this is rare for him.

Eyes:

Very clear gray, soft in their gaze.

Hair:

Long locks of warn blonde hair

Build:

His height, clothes, and long hair help to conceal that he has broad shoulders. He is not extremely muscular but he has not a lean frame either.

His legs are long and more muscular than his arms. ((Swimmer's body type))

Outfit:

When in elves' settlements he likes to wear colorful and bright robes of many layers in which he seems to sink. He often wears pieces of glass of his own making to accentuate his clothes and as a replacement for jewels for he would never wear gems, especially white gems for they resemble the Silmarill that bring the ruin to Doriath by Thingol's hand.

In the wilderness he switches this preference for a dark brown leather chestplate over a white robe. In those clothes, his build is more noticeable.

He only had in his possession one appropriate full metal armor set with Lothlorien motives that were gifted from Celeborn long years ago.
