Great base to add patches to
Size: X-Large, Color: Black
I've bought this jacket twice now (lost the first one...). Great base for my DIY patch jackets. I buy an XL even though it's a size too large for me. It's a standard denim jacket, not much to write home about. Good pocket size, and I appreciate the functional chest pockets.

Great PJs, but shorts are very short
Size: 3T, Color: Under the Sea
These PJs were super cute. I read reviews about the quality of the fabric not being great however I thought they were very soft, stretchy, comfortable and the color has stayed well through washes. They are lightweight and great for summer. MY ONLY CON: the shorts are very short and ride up even more so they end up looking almost like underwear. I wished the shorts were longer.
