Alterations By Lena

I've had many things altered here. They can be a bit more pricey at times, and yes, they aren't the most personable people, but if you know what you want you get it. I suspect people who are unhappy haven't been detailed about their desires. I've had denim and cotton/polyester blends, skirts, dresses, and a few shirts altered here and never been less than pleased.
When you enter just go right into the dressing room and put the outfit on then step back out. It's strange, I'm sure, but the women are busy and this is more efficient.
