Sorry - long post coming, but we have plenty of Tina's Skate Wear dresses at our rink right now, and I thought you might appreciate some first hand feedback. There are some really pretty dresses in your choices! I especially like the cut and colour of the last one, but can see it might not suit as it is.
The seller has listed your #3 and #4 as "youth" - I think she would probably be willing to make these in the larger adult size (you say you wear Adult Small), but it would be worth checking.
I've bought a Tina's dress myself, and there are many others at my rink. Here is my feedback, for what it's worth:
The goodThis seller is generally happy to change colours around, as long as she keeps the colour in stock. So I'd suggest you choose the colour and fabric of one of the dresses in her store (eg: "I would like this dress:
http://www.ebay.com/itm/CUSTOM-MADE-TO-FIT-ADORABLE-FIGURE-ICE-SKATING-DRESS-/150858318165?pt=US_Youth_Athletic_Apparel&hash=item231fdb4155 made in these colours:
http://www.ebay.com/itm/BEAUTIFUL-FIGURE-ICE-SKATING-DRESS-CUSTOM-MADE-FIT-/120872321966?pt=US_Youth_Athletic_Apparel&hash=item1c248d43ae" - I picked a colourway at random, but I hope you can see what I'm getting at.)
Her delivery is quick - the dress I bought arrived here less than 3 weeks after ordering.
Things to watch forBe careful asking for different fabrics if you want them to match properly (eg: blue velvet bodice and matching blue chiffon skirt) - unless it's something basic like black, the match can be a bit "off".
In the dress I bought, the briefs have limited cheek coverage at the back - if you lay the dress down, the front of the brief is very similar to the back. Fine for me as I don't have much in that department, but could be a problem if you're more blessed!
DecorationIn the Tina's dresses I have seen, it came as a bit of a surprise how much of the decoration isn't actually crystals (plastic or glass), but rather glitter paint and sequins. What's really surprising is how effective the glitter paint etc looks from a distance, so I wouldn't discount a dress from this seller just because "it doesn't have crystals".
A dress which has used the glue will smell quite strongly as it comes out of the packet. Something else to check - if glue has been used, can the dress be washed?
Re the 3 Tina's dresses you have linked:
Dress 2 looks to have sequins + seed beads (probably sewn on) below the bust. I couldn't zoom the camera in sufficiently to get a view of what has been used on the gathered bust area. The "straps" look to be sequins sewn on in lines, but again hard to tell.
Dress 3 has a band of stones at the top edge and around the neck, either glued or sewn on. The main bodice has the occasional silver sequin + seed bead (probably sewn on), and some leaf-shaped sequins glued or sewn on, or possibly the leaf shapes have been painted on with glitter paint; it's hard to tell without seeing the dress in person. The faint glitter on the hem of the skirt - which is really pretty! - is probably glitter paint.
Dress 4 looks to have a mixture of blue stones (either glued or sewn on) and silver sequins + seed beads, which are probably sewn on.
Hope all this helps, and have fun choosing!
