Monday

I decided to go for a more neutral look instead of jumping straight into color. I didn't want to feel totally uncomfortable in something pink or bright yellow, so I chose to wear a gray sweatshirt and jeans. It felt nice, actually! While I really wanted to grab my black jeans and dark combat boots, I resisted and felt OK about it in this outfit.

Tuesday

For the second day, I wore a light denim acid wash jacket and maroon pants. Yes, I can't believe I found maroon pants in the bottom of my closet drawers. This was a pretty simple look too, but I really, really wished that I had a black top or scarf to add.

Wednesday

Gradually, I moved to wearing a beige, sandy color. This was also a nice subtle change like my denim jacket, but again, I wish I had paired it with my leather booties or my black leather jacket. All in all, I felt kind of bland and didn't feel like I was uniquely expressing myself. Beige isn't the most exciting color, I suppose.

Thursday

I actually didn't have any other colored items left in my closet, so I had to borrow some of my boyfriend's clothes, because yes, his side of the closet is more colorful than mine. I decide to wear a striped red and white sweater and see if I felt super self-conscious when going out.

Friday

On Friday, I had to borrow another sweater from my boyfriend's closet. Although this time the color change was more subtle than the red and white, I still missed wearing black. The sweater was a nice change though and I'll have to admit that if I ever did decide to wear color again, it would probably be a dark blue like this one.

Saturday

Yes, you guessed it — this open cardigan is also from my boyfriend's closet. The red top is mine, but pairing it with the yellowish, striped cardigan was probably the most color I've worn in the past year. When going out, I actually didn't feel happier or brighter like I thought I would.

Sunday

Instead of borrowing from my boyfriend's closet, I decided to ask my 14-year old sister to help me out. She gave me a light pink crop top to wear and I tried to hold back my emotions. I don't wear pink, guys, and if I do, it's for a really good reason, like this one.
