Save or Splurge?

I consider myself to be a connoisseur of the online shopping world. It's what I do in my downtime--I don't necessarily buy anything, but I do enjoy scouring the web for the best deals, adding things I wish I could afford to my shopping bag, and imagining new pieces from every price point magically appearing in my closet.

When I'm seriously considering a new piece for my wardrobe, though, I try to find nearly identical items from two or three different price points, and make my decision based on whether I would rather save money on the item (cheap basics and trends always fall into this category) or splurge on it (usually an investment that I'll wear for years to come).

If you take a look in my closet, you'll notice right away that I'm obsessed with striped tees. They take up a significant amount of real estate, and for a good reason--they add a certain amount of parisian je ne sais quoi to any wardrobe, and they can be dressed up or down to suit your look!

Top shirt: Old Navy (on sale for $10.00!)
Bottom shirt: J. Crew ($29.50)
These shirts look pretty similar, but they are from different retailers and exist in slightly different price points ($10 versus $30).

Would you save or splurge on this colorful striped tee this summer? Personally, I am leaning towards the J. Crew shirt because the fabric looks weightier, plus I love the additional stripes on the sleeves!
