Take it back and hope they remember you.
Try to take it back before you try any self-repair.
Ok then, they close in 45 minutes so I'm outta here.
If they don't take it, you could put a small patch on it to cover the pull and keep it from snagging worse. I can sew well enough, but I'm sure as shit not fixing your rashguard for you.
I thought Lurs were noted for their weaving.
That's going to be a knit fabric, not a woven fabric.
If they refuse to exchange it, throw yourself on the ground and start sobbing.
Bleg: My phone just broke, and I need a new (or new to me/ used one). My carrier is Sprint. I don't need any bells and whistles, but I do want a clamshell. I'd also like it to be reliable and physically rugged. I want something cheap. Does anyone have any suggestions?
