If you can afford to clothe her with that line of clothes .. why not...You know what is appropriate for a 13 year old .. as long as you don't let her step over the line it should be fine.
Just keep in mind .. most 13 yr olds are already sexually active these days .. Depending on your daughter, she could like the clothes because 1) she just happens to like the style or 2) she understands how 'sexually charged' the image is and you will be enabling her 'adult' behaviour ..
I'm think'n .. If the likelihood is more like option 2, THEN, you might have a problem.
The permissive answers I see here scare me! A 13 year old is still a child, these answers will have her pregnant before she's 14. TV is glorifying pregnancy NOT motherhood! Oh well, thank God I wasn't a stupid baby pump like some of you were! Victoria's Secret on a child? NO WAY!!
i say as long as you make it known no sexy bras and thongs! girls usually wear sexy stuff because they have someone their gonna show it to. as long as its regular clothes nothings wrong with it :) cute clothes.
