Stretch out, size down but love the shorts.
Size: 8, Color: Ocean Breeze
Love these shorts. My favorites ever. I always always wear a size 8 in shorts. The 8 fit initially, but stretched out so much, I didn’t have to unbutton them to get them out. I bought 3 colors. I finally bought one in a size 6. Perfect fit, even if they do stretch a little. Returning the unworn ones, and replacing with size 6.

Love these shorts.
Size: 4, Color: Jet Black
Five inch for a great mom fit. Cute button closures for the pockets on the back, nice deep pockets. It’s hard to see in the video because they are black but they are the comfiest shorts. True to size. I’m a size 3-4 and the 4 fits perfect…. Even after washing and drying.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.
